Overview
flutter_js is a Flutter package that enables integration of JavaScript execution within Flutter applications. It leverages QuickJS on Android and JavaScriptCore on iOS, providing a cross-platform solution for running JavaScript code directly in the app. The package supports seamless interaction between Dart and JavaScript, allowing developers to execute scripts, call functions, and exchange data between the two environments. It's ideal for scenarios requiring dynamic scripting or embedding JavaScript logic without external dependencies.
Use cases
- Running dynamic JavaScript code in Flutter apps
- Integrating third-party JavaScript libraries
- Implementing scriptable plugins or extensions
- Enabling client-side JavaScript logic in hybrid apps
- Executing configuration-driven workflows
Key features
- Cross-platform JavaScript execution
- Dart-JavaScript interoperability
- QuickJS engine on Android
- JavaScriptCore on iOS
- Lightweight and fast runtime
Suitable for
- Developers needing JavaScript support in Flutter
- Apps requiring dynamic script execution
- Hybrid app components with JS logic
- Plugins that rely on JavaScript functionality
- Prototyping with executable scripts
Considerations
- Limited to JavaScript (not other languages)
- Platform-specific engine implementations
- Potential security risks with untrusted scripts
- Requires careful handling of async operations
- Memory usage may increase with complex scripts
