get_hooked_storage

Persistent GetValue objects backed by SharedPreferences.

Values created with Stored<T> can be used directly with ref.watch(), Get.it, RefPaint, and the rest of the get_hooked ecosystem while being automatically saved to and restored from local storage.

Usage

import 'package:flutter/material.dart';
import 'package:get_hooked/get_hooked.dart';
import 'package:get_hooked_storage/get_hooked_storage.dart';

// In main(), before runApp:
await Stored.init();

final counter = Stored('counter', 0);
final themeMode = Stored.enumValue(ThemeMode.values, ThemeMode.system);

class MyApp extends HookWidget {
  @override
  Widget build(BuildContext context) {
    final mode = ref.watch(themeMode);
    final count = ref.watch(counter);
    return MaterialApp(
      themeMode: mode,
      home: Text('count: $count'),
    );
  }
}

// Later:
counter.value = 1; // persists automatically
await themeMode.save(ThemeMode.dark); // or await the write

Supported types

• bool, int, double, String, List<String>
• Color and Color?
• Nullable versions of the above
• Enums via Stored.enumValue(values, initial)
• Custom types via Stored.custom(key, initial, encode: ..., decode: ...)

Initialization

Stored.init() must complete before any Stored value is read.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Stored.init();
  runApp(const MyApp());
}

See the library docs for Stored.enumValue, Stored.custom, and the save method.
