This project uses cargo make to combine the build commands for compiling the Rust sunshine module and linking it to the Flutter interface. This structure will eventually enable our substrate light client to talk directly to the Flutter interface (with no dependency on polkadot-js).
shekohex/flutterust is a generic template for Rust to Dart FFI
It is common for developers to get stuck setting the path to the Dart and Flutter SDKs after installation so take careful note of where these are installed. See the Dart docs: Configure PATH and environment variables for more info.
- Run
flutter doctorto verify that you have everything needed to build and run a flutter application.
You probably won't have a connected device and that's OK, you can pick your emulator in step (5) below.
- Install Cargo Make, Dart Bindgen and CBindgen (skip if you already have them installed)
$ cargo install cargo-make cbindgen
$ cargo install dart-bindgen --features cli
- Clone this repository.
These instructions assume that you have installed Android Studio or the flutter plugins for Android Studio.
-
Run the following commands in the root of the cloned repository.
$ cargo make android-dev # for android only using x86_64 emulator (run cargo make android to build for all android targets)
$ flutter run
These instructions assume that you may NOT have installed Android Studio nor the flutter plugins for Android Studio.
- Open the iOS emulator. This could be as simple as invoking the following command if you've set this alias before.
$ open -a simulator
You may have to specify File -> Open Device -> $MODEL once the simulator opens.
- In the root of the cloned repo, run the following commands.
$ cargo make ios --profile release # Release Build is Required since debug build is very big.
$ flutter run
After you run the application, all changed state is saved in the directory. To restart from the Generate Your Account screen, you must reset the cloned repo to head (git reset --hard HEAD), delete the app from the simulator and do the last three commands listed above again.
