tricks library

Useful features built on top of Jolt.

This library provides commonly used utilities and extensions that enhance the core Jolt reactive system with practical functionality.

Features

• ConvertComputed: Type-converting computed signals
• PersistSignal: Signals that automatically persist to storage

Usage

import 'package:jolt/tricks.dart';

// Type-converting signal
final count = Signal(0);
final textCount = ConvertComputed(
  count,
  decode: (int value) => value.toString(),
  encode: (String value) => int.parse(value),
);

// Persistent signal
final theme = PersistSignal(
  read: () => SharedPreferences.getInstance()
    .then((prefs) => prefs.getString('theme') ?? 'light'),
  write: (value) => SharedPreferences.getInstance()
    .then((prefs) => prefs.setString('theme', value)),
);
