global_snack_bar

Description:

global snack bar

global_snack_bar #
Provides a class for a global snack bar. This makes it convenient to summon a SnackBar with simple code, regardless of the Scaffold that is currently visible.
This is useful for cases such as intermittently checking the network connection — cases where you don't know what Scaffold will be visible before needing to show a SnackBar.
Just wrap your content in GlobalMsgWrapper.
Make sure that your content is a child of a Scaffold.
Then, from anywhere, use the following to show a SnackBar:
GlobalSnackBarBloc.showMessage(
  GlobalMsg("hello", bgColor: Colors.cyanAccent),
); copied to clipboard
