In Flutter, how can I check if I am releasing (dispose) everything correctly? I am building an application and I have the feeling that the simulator is getting slower after a series of hot reloads. Many thanks for your answers.

Dart comes with a debugger called <code>Observatory</code>. It does a bit of everything you need. From CPU/Memory usage, to time spent on each functions. Even breakpoints and code coverage. When running your flutter app, it's available by default on the localhost. When running <code>flutter run</code> in the terminal, the port will be displayed. On vscode with <code>Dart code</code> extension, you'll need to use the command <code>Open Observatory timeline</code>. <img src="https://i.stack.imgur.com/1P3c6.png" alt="enter image description here">
