Dive deep into the inner workings of Flutter in this 44-minute conference talk from Flutter Europe. Explore how Flutter transforms widgets into pixels by examining the layers beyond the widgets-layer. Begin with a look at building an app using bare dart.ui and its relation to OpenGL operations. Introduce the first layer of abstraction, RenderObjects, and investigate different RenderObjects within the framework. Uncover the connection between widgets and RenderObjects through Elements, and gain insight into the BuildContext and how everything interconnects. Conclude by creating a custom RenderObject with a unique layout and paint algorithm. Perfect for developers seeking a comprehensive understanding of Flutter's architecture and rendering process.
