How to solve moor error with provide and buildcontext?

Question

Error provider with moor database still appears after adding provide as well.

After click on Save

  Widget buildButton() {
    final isFormValid = title.isNotEmpty && minutesPerDay.isNotEmpty && timeGoal.isNotEmpty;

    return Padding(
      padding: EdgeInsets.symmetric(vertical: 8, horizontal: 12),
      child: ElevatedButton(
        style: ElevatedButton.styleFrom(
          onPrimary: Colors.white,
          primary: isFormValid ? null : Colors.grey.shade700,
        ),
        onPressed: addOrUpdateGoal,
        child: Text('Save'),
      ),
    );
  }

addOrUpdate uses

 Future addGoal() async {
    final database = Provider.of<AppDatabase>(context, listen: false);
    final goal = Goal(
      id: 0,
      goal: timeGoal,
      intenseGoal: minutesPerDay,
      timeGoal: timeGoal,
      initialDate: initialDate,
      editDate: editDate,
      completed: isImportant,
      color: color,
    );
    database.insertGoal(goal);
  }

Error appears and nothing is added to database:

Error: Could not find the correct Provider<AppDatabase> abov
e this AddEditGoalPage Widget

E/flutter (29178): - You used a `BuildContext` that is an ancestor of the provider you are trying to read.
E/flutter (29178):
E/flutter (29178):   Make sure that AddEditGoalPage is under your MultiProvider/Provider<AppDatabase>.
E/flutter (29178):   This usually happens when you are creating a provider and trying to read it immediately.

added this lines:

return Provider(
      create: (_) => AppDatabase(),
      child: Scaffold(

class AddEditGoalPage extends StatefulWidget {
  final Goal? goal;

  const AddEditGoalPage({
    Key? key,
    this.goal
  }) : super(key: key);

  @override
  _AddEditGoalPageState createState() => _AddEditGoalPageState();
}

// TO EDIT values
class _AddEditGoalPageState extends State<AddEditGoalPage> {
  final _formKey = GlobalKey<FormState>();
  late bool isImportant;
  late String timeGoal;
  late String title;
  late String minutesPerDay;
  late String color;
  late String initialDate;
  late String editDate;

  get database => AppDatabase;


  @override
  void initState() {
    super.initState();
// to check
    isImportant = widget.goal?.completed ?? false;
    timeGoal = widget.goal?.timeGoal ?? '';
    title = widget.goal?.goal ?? '';
    minutesPerDay = widget.goal?.intenseGoal ?? '';
    color = widget.goal?.color ?? '';
    initialDate = widget.goal?.initialDate ?? '';
    editDate = widget.goal?.editDate ?? '';

  }

  @override

    return Provider(
