I've a SnackBar:

SnackBar(
  content: Text('FooBar'),
  action: SnackBarAction(
    label: 'Action',
    onPressed: null,
  ),
);

How can I change the font size of 'Action'?

You can customize the Snackbar's action font size by changing the button theme in the app's global theme. This is because the Snackbar's action is considered as a button. For example, set:

MaterialApp(
  theme: ThemeData(
    textTheme: TextTheme(
      button: TextStyle(fontSize: 16.0),
    ),
  ),
  home: const MyHomePage(title: appName),
);

The actions in Snackbars will be affected as desired.
