- Directories need to be lowercase.
## Code style:
- We recommend using Android Studio for coding. We are using the Android Studio auto styling with ctrl+alt+shift+L.
Please use code formatting. You can use VSCode or Android Studio. On other editors you need to run:
```
flutter format lib/**/*/*.dart
```
## Code quality:
- Don't repeat yourself! Use local variables, functions, classes.
