This repository serves as a template for Flutter projects calling into native Rust
libraries via flutter_rust_bridge.
To begin, ensure that you have a working installation of the following items:
- Flutter SDK
- Rust language
flutter_rust_bridge_codegencargo package- Appropriate Rust targets for cross-compiling to your device
- For Android targets:
- Install cargo-ndk
- Install Android NDK 22, then put its path in one of the
gradle.properties, e.g.:
echo "ANDROID_NDK=.." >> ~/.gradle/gradle.properties
- For iOS targets:
- Install cargo-xcode
- Web dependencies for the Web
Then go ahead and run flutter run (for web, run dart run flutter_rust_bridge:serve instead). When you're ready, refer to our documentation
here to learn how to write and use binding code.
Once you have edited api.rs to incorporate your own Rust code, the bridge files bridge_definitions.dart and bridge_generated.dart are generated using the following command (note: append --wasm to add web support):
flutter_rust_bridge_codegen --rust-input native\src\api.rs --dart-output .\lib\bridge_generated.dart --dart-decl-output .\lib\bridge_definitions.dart
flutter_rust_bridge_codegen --rust-input native/src/api.rs --dart-output ./lib/bridge_generated.dart --dart-decl-output ./lib/bridge_definitions.dart
If you would like to generate boilerplate for using flutter_rust_bridge in your existing projects,
check out the flutter_rust_bridge brick
for more details.

alle obigen toolchains müssen zum path hinzugefügt werden, da llvm sie sonst im build prozess nicht findet
