Features

A safe way to call setState without having to worry about mounted.

Don't use this to get around the Flutter framework. Only use this if for example you are doing async stuff and can't use FutureBuilder or something similar.

Usage

Add MountedState or MountedStateOverride like any other mixin.

class _MyHomePageState extends State<MyHomePage> with MountedState, MountedStateOverride

MountedState adds setMountedState which you can use instead of setState.

MountedStateOverride will override setState.

Both always check if the widget is mounted before calling setState.
