flutter_pytorch_hiragana

A Flutter plugin to use my ml model that classify japanese hiragana.

The model used for classification is MobileNetV3 Small, obtained from torchvision.models. It is fine-tuned using the ETL-7 Character Database from http://etlcdb.db.aist.go.jp/.

To prevent crashes in release mode when using a PyTorch-based Flutter plugin, add the following lines to (your flutter project dir)/android/app/build.gradle file:

// (your flutter project dir)/android/app/build.gradle
android{
    buildTypes {
        release {
            shrinkResources false
            minifyEnabled false

            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}
