So after reading some positive review on Google Play saying that "this is an excellent app, too bad it is no longer updated", I've decided to make an update and also make this app open source. Maybe someone sometime will decide to contribute to this project. But as the existing repo contained some sensitive data, that I've pushed due to lack of experience, I had to make a new one. And if creating a new repo, why not rewrite the app from scratch? Without further delay behold my new Lightmeter app inspired by Material You (a.k.a. M3) # Screenshots

# Build ## Available flavors Building with prod flavor requires `DefaultFirebaseOptions` to be present in the _lib/firebase_options.dart_ If you don't want to create your own firebase app, you end up with only dev flavor. ## IAP repo import As part of the app's functionallity is in the private repo, you have to replace this lines in _pubspec.yaml_: ```yaml m3_lightmeter_iap: git: url: "https://github.com/vodemn/m3_lightmeter_iap" ref: main ``` to this: ```yaml m3_lightmeter_iap: path: iap ``` After that run `flutter pub get` as usual. For the first run it will be necessary to open _iap/_ folder and run `flutter pub get` from there. # Contribution To report a bug or suggest a new feature open a new [issue](https://github.com/vodemn/m3_lightmeter/issues). In case you want to help develop this project you need to follow this [style guide](doc/style_guide.md). # iOS Limitations A list of features, that Android version of the app has and that iOS does not. ## Incident light metering Apple does not provide API for reading Lux stream form the ambient light sensor. Lux can be calculated based on front camera image stream, but this would be a reflected light. So there is no way incident light metering can be implemented on iOS. ## Volume buttons action This can be [implemented](https://stackoverflow.com/questions/70161271/ios-override-hardware-volume-buttons-same-as-zello) but the app will be rejected due to [2.5.9](https://developer.apple.com/app-store/review/guidelines/#software-requirements)
