We wrote BSC News mobile app for Android and iOS in 2021 in a team of two developers. With this app users can read and bookmark their favorite articles, view market info for many cryptocurrencies, and receive important push notifications.
BSC News is written in Flutter. API definition for this app was provided as OpenAPI, and we used code generation for Dart client. Users can bookmark articles for later read. Notifications for interesting articles or cryptocurrency price updates are delivered over OneSignal and can be customized or turned off in app's settings.
