Flutter vs React Native (for building IoT Applications)

Good day Experts! I need your valuable suggestions regarding a very important decision in my development life. I need to know which framework is best suitable for IoT applications like communicating with BLE (Bluetooth Low Energy) devices/microcontrollers (while supporting both ios and android platforms without going into problems and without doing anything extra), Classical Bluetooth communications, MQTT and HTTP communications easily and efficiently, Firebase integration and IoT platforms integration (AWS,Google IoT core) and all other IoT related stuff 🙂
