flutter/flutter-build-responsive-layout

LayoutBuilder、MediaQuery、またはExpanded/Flexibleを使用して、さまざまな画面サイズに適応するレイアウトを作成します。モバイルとタブレット/デスクトップの両方のフォームファクターでUIを美しく表示する必要がある場合に使用します。

flutter-build-responsive-layout とは?

このスキルは、Flutterアプリケーションにおいて、異なる画面サイズやデバイスフォームファクターに自動的に適応するレスポンシブレイアウトを構築するための包括的なガイドを提供します。主に`LayoutBuilder`、`MediaQuery`、`Expanded/Flexible`といったFlutterの強力なレイアウトウィジェットを活用し、モバイル、タブレット、デスクトップの各プラットフォームで一貫したユーザーエクスペリエンスを実現します。このスキルは、特にクロスプラットフォーム開発においてUIの可読性と操作性を維持するために重要であり、アプリが多様な画面環境で最適に表示されることを保証します。Flutterフレームワークをターゲットとしており、Claude Code、Cursor、CodexなどのAIエージェントで使用できます。スキルドキュメント(SKILL.md)では、各ウィジェットの具体的な使用方法、コード例、ベストプラクティスが説明されており、開発者はこれを参照することで効率的にレスポンシブデザインを実装できます。
