Flutter

Thermion requires Android SDK version 22, so change your app/android/build.gradle to match this version or higher：

 defaultConfig {
    ...
        minSdk = 22
    ...
    }

flutter run -d chrome --web-header Cross-Origin-Embedder-Policy=require-corp --web-header Cross-Origin-Opener-Policy=same-origin
