The Flutter framework operates by writing applications in Dart language, compiling them into native code, and running directly on the operating system, rather than relying on traditional WebView rendering.<\/p>\n

In concrete terms, the working principle of the Flutter framework can be divided into the following steps:<\/p>\n

    \n
  1. Developing applications with Dart language: Using the Flutter framework, developers can write applications using the Dart language. Dart language is a cross-platform programming language that shares syntax features with Java and JavaScript.<\/li>\n
  2. Compile to native code: Utilize the tools provided by the Flutter framework to compile Dart code into native machine code. This allows the application to run directly on the operating system without the need for rendering through WebView.<\/li>\n
  3. Create a rendering tree: The Flutter framework converts the UI description of an application into a rendering tree using the Skia graphics engine. The rendering tree contains all the UI components of the application along with their corresponding style information.<\/li>\n
  4. Layout and drawing: The Flutter framework performs layout and drawing operations on the rendering tree, calculating the position of each component on the screen based on their UI component location and style information, and then rendering them.<\/li>\n
  5. Handle user interactions: The Flutter framework manages user touch, swipe, click, and other interaction operations by utilizing the underlying platform’s input event system. When users interact with the application, the Flutter framework updates the rendering tree and performs layout and drawing operations again.<\/li>\n<\/ol>\n

    During the entire process, the Flutter framework utilizes the high-performance Skia graphic engine, enabling applications to quickly respond to user interactions and achieve fluid animation effects. Additionally, the Flutter framework also provides a rich library of UI components and development tools to help developers quickly build high-quality mobile applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
