    title: 'Demo',
    home: Text('hi'),
  ));
}

Solution

  • If what you're asking is how to run flutter on web such that it consumes less memory at the outset, the answer may be to run it in release mode using the html renderer rather than the canvas renderer. (More on renderers: https://flutter.dev/docs/development/tools/web-renderers)

    flutter run -d chrome --web-renderer html --release

    This worked for me. Running a simple hello world app, my heap was measuring ~150mb even in release mode. Then, I switched to html renderer. Now, in debug mode the heap is ~60mb. In release mode it's ~7mb.
