Rework the drawer

- Cache widgets with Riverpod
- Fix apps not launched when in release mode.

Apparently Flutter copies the environment variables when the engine is
started, in release mode. Now, environment variables like
WAYLAND_DISPLAY are set before starting the Flutter engine.

- Fix an exception with the newest version of Riverpod.
