Flutter · Expert - architecture, internals and edge cases

• Architecting an app: UI, logic, dataStructure a Flutter app in watertight layers with the repository pattern and typed sealed results.
• Animations: implicit and explicit under the hoodUnderstand the internal mechanics of implicit animations and finely drive your own AnimationController.
• Performance: const, rebuilds, keys and DevToolsEliminate useless rebuilds thanks to const, keys and reconciliation, then measure with DevTools.
• Adaptive: LayoutBuilder, MediaQuery and platformsBuild interfaces that adapt to the parent's constraints, to the window and to each OS's conventions.
• Tests: Dart unit tests and widget testsTest logic and widgets with hand-written fakes, a simulated clock and the right pump reflexes.
