This code creates a safe area that consists of a Column and a TextButton. The Column has two children, the first of which is a TextButton which will be triggered when the user presses it. The second child is a const Text which is displayed when the TextButton is clicked.
return SafeArea(
child: Column(
children: [
const Text('Please verify your email address'),
TextButton(
onPressed: () async {
final user = FirebaseAuth.instance.currentUser;
await user?.sendEmailVerification();
},
child: const Text('Send email verification'),
)
],
),
);
