A simple Flutter app for displaying stories retrieved from Hacker News. Uses the provider package along with MobX to managing the architecture
The app demonstrates
- Using MobX for managing UI state where stores function as view models that may talk to other services i.e. how to follow the widget -> store -> service structure
- Using
providerorganise stores and inject them into the appropriate widgets. Services are injected into the stores viaprovideras well. Both of these are done using theConsumerwidget (andConsumer2when injecting in two dependencies) - Using
providerto resolve dependencies using the staticProvider.of<T>(context)method - How to load more items into a
ListViewbased on scroll position by invoking an action in MobX - Opening stories using the url_launcher package with the ability to load them in the browser instead of doing so "in-app"
- Toggling between dark and light theme
- Using custom fonts
- Using a Cupertino widgets within a material app
NOTE: when the app was originally written, the ProxyProvider class wasn't available yet in the provider package. It should be possible to update the app to make of use of it
When trying to debug on your machine via an Android device, you'll currently need to go to android/app/build.gradle and modify the contents to comment out/remove the store release related configuration. The latter configuration is there as I currently have this setup with Codemagic to deploy to the Google Play store. The relevant sections look like as follows
// beginning of config for store release
signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
storePassword keystoreProperties['storePassword']
}
}
buildTypes {
release {
signingConfig signingConfigs.release
minifyEnabled true
useProguard true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
// end of config related to store release
// for debugging
/*buildTypes {
release {
// 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
}
}*/
After modifying it so it can be debugged, it'll look like as follows
// beginning of config for store release
/*signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
storePassword keystoreProperties['storePassword']
}
}
buildTypes {
release {
signingConfig signingConfigs.release
minifyEnabled true
useProguard true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}*/
// end of config related to store release
// for debugging
buildTypes {
release {
// 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
}
}
