show dialog/snackbar etc

It will. There's nothing wrong with it.

You can use context too.

i could do
useEffect(() { if (state == 5) { showDialog( context:context ); } }, [state] );
is it valid to use context in useEffect?

[rrousselGit]

No this won't do.
We need a useAsyncEffect, which calls the callback after the build finished.

A lazy implementation could be:

void useAsyncEffect(VoidCallback cb, [List<dynamic> keys]) {
  useEffect(() => Future.microtask(cb), keys);
}

WidgetsBinding.instance.addPostFrameCallback(); won't work, i guess :)?
