In addition to the UI, many real-life mobile apps rely on advanced OS-level functionality, such as GPS coordinates, Bluetooth connectivity, sensor data collection, authorization management, credential service, etc. Many of these are accessible via a ready-to-use plugin sponsored by Google while creating a Flutter program. There will be instances of the application depending on a feature at the OS level that is not yet usable as a plugin. Flutter offers an easy to use means of creating connectivity across platform channels between platform-native code and Dart. This way, with only a little extra work on the native side, you can incorporate everything a native app can do.
