Specifically, configure the Flutter development environment, set the project structure and project configuration file; create a Flutter project according to the project structure and project configuration file; wherein the Flutter project includes a directory corresponding to each business module; write the business function code corresponding to the business module according to the preset implementation method under the directory corresponding to each business module, and generate each business module; establish a UI interface using a responsive design method based on a pre-established UI component library; package each business module and UI interface to generate an application installation package and publish it to each platform. In this way, the development process of multi-person real-time collaborative applications is simplified, the development efficiency and application performance are improved, and user privacy and data security are guaranteed.
[0045] The following describes in detail the Flutter-based application development method and device provided by the embodiments of the present disclosure through specific embodiments in conjunction with the accompanying drawings.
[0046] Figure 1 A flowchart of a Flutter-based application development method provided in an embodiment of the present disclosure is shown. The method 100 includes the following steps:
[0047] S110, configure the Flutter development environment, set the project structure and project configuration file; create a Flutter project according to the project structure and project configuration file; wherein the Flutter project includes a directory corresponding to each business module.
[0048] In some embodiments, the Flutter development environment is configured to ensure that applications can be developed and tested on Android, iOS, and Web platforms.
[0049] S120, writing the business function code corresponding to the business module according to the preset implementation method in the directory corresponding to each business module to generate each business module.
[0050] In some embodiments, the business module includes:
[0051] Real-time collaboration core module, standardized component module, permission management module, version control module, cross-platform support module, plug-in management module, data security and privacy settings module.
[0052] In some embodiments, the real-time collaboration core module includes a data synchronization module and a conflict handling module; wherein,
[0053] The data synchronization module is used to achieve real-time data synchronization through the WebSocket protocol and data merging strategy, ensuring that operations of multiple users on the same data on different devices can be reflected in a timely manner;
[0054] The conflict handling module is used to adopt an optimistic concurrency control strategy and interact with the data synchronization module and the plug-in management module to avoid data conflicts when multiple users operate on the same data and merge operations performed by multiple users on the same data.
[0055] In some embodiments, by interacting with the data synchronization module and the plug-in management module, data conflicts when multiple users operate on the same data are avoided and operations performed by multiple users on the same data are merged, including:
[0056] Check the data version number before executing the user operation; if the data version numbers are consistent, execute the user operation and update the data version number through the data synchronization module; if the data version numbers are inconsistent, use the conflict detection algorithm to detect data conflicts through the data synchronization module and send the data conflicts to the plug-in management module for processing, so that the plug-in management module can use the conflict resolution algorithm (such as a merge strategy based on timestamps) to resolve the data conflicts and return the resolution results to the data synchronization module, and merge the operations performed by multiple users on the same data through the data synchronization module;
[0057] Specifically, the conflict handling module adopts an optimistic concurrency control strategy, that is, it assumes that data conflicts will not occur in most cases during the execution of user operations. Therefore, it is only necessary to detect whether data conflicts occur before executing user operations. The specific method for detecting data conflicts is as follows:
[0058] For a single application, the version number of the data to be operated (i.e., the same data mentioned below) is checked before executing the user operation; if the version number of the data is consistent with the data version number checked by other users before the data synchronization module in the single application operates on the same data (indicating that there is no data conflict before the user and other users operate on the same data), the data synchronization module in the application executes the user operation, and at the same time updates the version number of the data to a new data version number by adding a timestamp, using a hash value, etc., and sends it to the data synchronization module in the application used by other users through an API interface or communication protocol, so as to synchronize the operations performed by the user and other users on the same data later;
[0059] If the version number of the data is inconsistent with the data version number checked by other users before the data synchronization module in a single application operates on the same data (indicating that a data conflict occurs before the user and other users operate on the same data), the data synchronization module in the application uses a conflict detection algorithm to detect the data conflict generated before the user and other users operate on the same data, and sends the data conflict to the plug-in management module of the application for processing; the plug-in management module of the application uses a conflict resolution algorithm (such as a merge strategy based on a timestamp) to resolve the data conflict and returns the resolution result (i.e., the data state after the data conflict is resolved) to the data synchronization module of the application, and the data synchronization module merges the data generated before the user and other users operate on the same data according to the resolution result (for example, two users modify different parts of the same document, and the data synchronization module merges these modifications into the same document based on the merge strategy of a timestamp) and assigns a new data version number to the merged data by adding a timestamp, using a hash value, etc., to ensure that the merged data has the latest version identification; the new data version number and the merged data are sent to the data synchronization modules in the applications used by other users respectively through an API interface or a communication protocol, so as to synchronize the operations performed by the user and other users on the same data later;
[0060] Furthermore, the conflict handling modules in the applications used by other users respectively check the version number of the data to be operated before executing the corresponding user's operation on the same data, and send the checked data version number to the data synchronization module in the single user through the API interface or communication protocol;
[0061] The data version number is an identifier used to identify the data status. It can be generated by a timestamp or hash value, etc. It can reflect the status or modification history of the data at a certain point in time.
[0062] The new data version number can be an incrementing numeric value, the current timestamp, or other unique identifier.
[0063] In some embodiments, the standardized component module is used to create a standardized component library and synchronously update the status of each component in the standardized component library through a status management tool;
[0064] Furthermore, the standardized component library includes real-time collaboration components such as shared text editors and shared whiteboards;
[0065] State management tools include Provider and Riverpod;
[0066] The status of each component in the standardized component library is updated synchronously through the status management tool using real-time communication technology.
[0067] In some embodiments, the standardized component library allows developers to extend and customize component functions according to specific needs, and has extensibility and reusability.
[0068] In some embodiments, the cross-platform support module is used to identify different platforms and perform adaptation and optimization for different platforms.
[0069] In some embodiments, the cross-platform support module may also use a platform channel (Method Channel) to interact with native code to implement platform-specific functions.
[0070] In some embodiments, a plug-in management module is used to interact the custom plug-in with the real-time collaboration core module and the standardized component module through a standard API and manage the custom plug-in;
[0071] Furthermore, custom plug-ins are managed, including:
[0072] Download and install plugins, enable or disable plugins, and update plugins.
[0073] In some embodiments, the plug-in management module is used to interact the custom plug-in with the real-time collaboration core module and the standardized component module through the standard API, including:
[0074] The plug-in management module is used to create custom plug-ins according to the developer's specific needs, and add the custom plug-ins to the standardized component library in the standardized component module to expand the functions of each component in the application; it is also used to interact the custom plug-ins with the real-time collaboration core module through the standard API to achieve real-time data synchronization and avoid data conflicts.
[0075] In some embodiments, the permission management module is used to assign corresponding operation permissions to different users, such as viewing, editing, and management permissions.
[0076] In some embodiments, the permission management module is also used to perform user identity authentication using third-party services such as Firebase Auth.
[0077] In some embodiments, the data security and privacy setting module is used to ensure the security of data transmission through end-to-end encryption methods (such as AES, RSA), and is also used to ensure that users set data sharing scope and collaboration permissions as needed through privacy setting options.
[0078] In some embodiments, the version control module is used to record the historical versions of application changes so that users can view, compare or return to the historical versions;
[0079] Record the historical version of application changes, including:
[0080] Use persistent storage (such as SQLite, Hive) to save historical version data of application changes.
[0081] S130, establishing a UI interface using a responsive design method according to a pre-established UI component library.
[0082] In some embodiments, the UI component library can ensure that the UI interface style and interaction logic are consistent;
[0083] The responsive design method ensures that the UI interface can adapt to the screen size and resolution of different devices to provide users with the best experience.
[0084] S140, packaging the business module and UI interface to generate an application installation package and publishing it to various platforms.
[0085] In some embodiments, before packaging the business module and the UI interface to generate an application installation package and publishing it to each platform, the process includes:
[0086] Test each business module separately;
[0087] If all tests are successful, use the Flutter command line tool to package the business module and UI interface to generate an application installation package and publish it to each platform;
[0088] If there is a test failure, repair the business function code corresponding to the business module that failed the test, and repeat the test on the repaired business module until the test succeeds.
[0089] According to the embodiments of the present disclosure, configure the Flutter development environment, set the project structure and project configuration file; create a Flutter project according to the project structure and project configuration file; wherein the Flutter project includes a directory corresponding to each business module; write the business function code corresponding to the business module according to the preset implementation method under the directory corresponding to each business module, and generate each business module; establish a UI interface using a responsive design method based on a pre-established UI component library; package each business module and UI interface to generate an application installation package and publish it to each platform. In this way, the development process of multi-person real-time collaborative applications is simplified, the development efficiency and application performance are improved, and user privacy and data security are guaranteed.
