如何在 flutter dart 中访问提供程序中的 getter

Question

I have assigned the value from changeNotifierproxyProvider to the Company provider. I have to access the value from the Company class provider to screen widget.

My code is

Company.dart

class Company with ChangeNotifier{
final bool _companyCreated;

Company(this._companyCreated);

get isCompanyCreated{
return _companyCreated;
}

ProducerSignUpScreen.dart

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
import 'package:scopemobileapp/providers/company.dart';

class ProducerSignUpScreen extends StatefulWidget {
static const routeName = '/producer-signup';

}

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

class _ProducerSignUpScreenState extends State<ProducerSignUpScreen> {
**bool companycreated = Company.isCompanyCreated();**
}

i want to call the isCompanyCreated from the producer sign up screen and assign the value to variable companyCreated

I guess you can use Provider.of<Company>(context); in your build method so you can have access to an instance of Company class. Also, don't forget to provide Company class in the nearest parent of the children that use Provider.of(context) so InheritedWidget can access the instance you want to use.

Widget build(BuildContext context){
      final company = Provider.of<Company>(context);
      bool companycreated = company.isCompanyCreated;
      return .....

}
