Material Month/Year Picker

The month year picker inspired by the Flutter's date picker design.

Quick Start

Open your pubspec.yaml file and add this entry:
```
month_year_picker: ^0.3.0+1
```
OR just run flutter pub add month_year_picker using your preferred terminal app.
Then run flutter pub get.

Import this library into your code:

import 'package:month_year_picker/month_year_picker.dart';

Additionally, ensure your MaterialApp refers to the following localizationsDelegates:

    GlobalMaterialLocalizations.delegate,
    MonthYearPickerLocalizations.delegate,

Usage in code:

final selected = await showMonthYearPicker(
  context: context,
  initialDate: DateTime.now(),
  firstDate: DateTime(2019),
  lastDate: DateTime(2023),
);

`initialDate`	Must not be `null` and must fall between the `firstDate` and `lastDate`. The `initialDate` will be truncated to its `year` and `month` components. When the month/year picker is first displayed, it will show the month/year of the `initialDate`, with `initialDate` selected.
