Oref

Based on the Oref docs and repository examples. Use BuildContext-bound APIs inside widget builds when possible.

Preferences

• Match the user's language.
• Prefer concise, runnable snippets over long explanations.
• Use signal(context, ...)/computed(context, ...)/effect(context, ...) inside build.
• Use null context only outside widgets, and keep the dispose handle.
• Use SignalBuilder to scope rebuilds to small subtrees.
• Use batch() for multi-step updates or collection mutations.
• Avoid writing to signals inside computed getters.
• Call hooks unconditionally at the top level of a build scope.

Quick Reference

Minimal widget

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

class Counter extends StatelessWidget {
  const Counter({super.key});

  @override
  Widget build(BuildContext context) {
    final count = signal(context, 0);
    final doubled = computed(context, (_) => count() * 2);

    return Column(
      children: [
        Text('Count: ${count()} / ${doubled()}'),
        TextButton(onPressed: () => count.set(count() + 1), child: const Text('Add')),
      ],
    );
  }
}

Key imports

Response workflow

1. Identify the question type and open the matching reference.
2. Provide the smallest snippet that answers the question.
3. Ask for missing context only if required (Flutter version, target platform, existing code).
4. Avoid guessing versions; read the user's pubspec.yaml or ask them to confirm.
