Locale functionality doesn't run properly

[frmunozr10]

Hello,
When I fill up locale variable with a location different to Locale('en') I've run into an issue:

I/flutter ( 5182): When the exception was thrown, this was the stack:
I/flutter ( 5182): #0 Object.noSuchMethod (dart:core-patch/object_patch.dart:50:5)
I/flutter ( 5182): #1 _DatePickerDialogState.didChangeDependencies
package:date_range_picker/date_range_picker.dart:1033

Localizations variable in date_range_picker.dart file is null.

If I change Locale('fr') to Locale('en') localizations variable is not null and all run properly.

Code:
final List picked = await DateRangePicker.showDatePicker(
context: context,
initialFirstDate: DateTime.now(),
initialLastDate: (DateTime.now()).add(Duration(days: 2)),
firstDate: (DateTime.now()).subtract(Duration(days: 1)),
lastDate: (DateTime.now()).add(Duration(days: 365)),
locale: Locale('fr')
);

Any way around this?

Thanks.

config MaterialLocalizations can solve this problem

1.pubspec.yaml add dependencies

flutter_localizations: sdk: flutter
2.main.dart
import 'package:flutter_localizations/flutter_localizations.dart';
//MaterialApp
//增加国际化 localizationsDelegates: [ //此处 GlobalMaterialLocalizations.delegate, GlobalWidgetsLocalizations.delegate, ], supportedLocales: [ //此处 const Locale('zh', 'CH'), ]

3 date_range_picker
locale: const Locale('zh', 'CH')

then it can work
