Learn that Riverpod is a safer alternative to Provider.

What is Riverpod?

Riverpod is the safe and testable alternative to the Provider package. Unlike Provider, it does not depend on BuildContext; it is accessed everywhere via ref. It reduces build-time errors and forces explicit distribution.

import 'package:flutter_riverpod/flutter_riverpod.dart';

The app root is wrapped with ProviderScope.

ProviderScope and ref

ProviderScope wraps the app root and manages the lifecycle of each provider. ref is the object used to access providers; it is used via ref.watch and ref.read.

void main() {
  runApp(ProviderScope(child: MyApp()));
}

Providers are declared at the top level.

Exercise Import Riverpod and wrap the root

Import the flutter_riverpod package. In main, wrap the root with ProviderScope. In main, call print('riverpod hazır').

Show example solution

import 'package:flutter/material.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';

void main() {
  print('riverpod hazır');
  runApp(ProviderScope(child: MyApp()));
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(body: Center(child: Text('Merhaba Riverpod'))),
    );
  }
}

It does not depend on BuildContext — Riverpod does not depend on BuildContext; it is accessed via ref from anywhere. Thus it is safer than the Provider package which depends on BuildContext.
