# FFIgen + JNIgen pedometer
This is a demo for some of our tooling around
calling platform APIs directly from dart code.
This repository represents a demo of a plugin that leverages FFIgen & JNIgen.
There is also an example pedometer app that
uses the bindings generated from these tools.
- [FFIgen](https://pub.dev/packages/ffigen) is used to generate
bindings for C, Objective-C and Swift APIs.
- [JNIgen](https://pub.dev/packages/jnigen) is used to generate
bindings for Java and Kotlin APIs.
**These tools are both experimental and are currently a work in progress.**
If you find any issues or have feedback,
please file it on the corresponding GitHub repositories.
## Re-generating bindings
The bindings that allow the Dart code to call the platform code have
already been generated in the [`\lib` folder](./lib).
You can regenerate them by following the steps below:
### FFIgen
Configuration of FFIgen for the
[CoreMotion framework](https://developer.apple.com/documentation/coremotion)
is in the [`ffigen.yaml` file](./ffigen.yaml).
FFIgen currently does not support autogenerating code to handle callbacks.
So, there are a few extra steps needed to
appropriately handle callbacks in Objective-C.
You can read more about this limitation on
[dart.dev](https://dart.dev/interop/objective-c-interop#callbacks-and-multithreading-limitations).
```bash
dart run ffigen --config ffigen.yaml
```
### JNIgen
Configuration of JNIgen for the
[HealthConnect API](https://developer.android.com/guide/health-and-fitness/health-connect)
is in the [`jnigen.yaml` file](./jnigen.yaml).
1. Build an Android APK file from the example app.
Currently, JNIgen requires at least one APK build
to obtain the classpaths of Android Gradle libraries.
```bash
cd example && flutter build apk
```
2. Return to the `/pedometer` directory and run `jnigen`:
```bash
cd .. && dart run jnigen --config jnigen.yaml
```
## Running the example app
The example app is located in the [`/example`](./example) directory,
and the following commands assume they are being run from that location.
Note that step counting is only available on physical devices.
### iOS
- Run `flutter run` and choose your physical device.
- Allow the *pedometer* app access to step counting.
### Android
- Make sure that [Google Fit](https://play.google.com/store/apps/details?id=com.google.android.apps.fitness)
is installed (to ensure that steps are being counted).
- Run `flutter run` and choose your physical device.
- Install [Health Connect](https://play.google.com/store/apps/details?id=com.google.android.apps.healthdata)
and grant access to Google Fit and the *jni_demo* app.
## Project structure
* `src`: Contains the native source code, and a `CMakeLists.txt` file for
building that source code into a dynamic library.
* `lib`: Contains the Dart code that defines the API of the plugin and
calls into the native code using `dart:ffi`.
* platform folders (`ios` etc.): Contain the build files for
building and bundling the native code library with the platform application.
* `example`: Contains the native source code for building
that source code into a dynamic library.

# Launch Screen Assets
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
