Bugfix for Example app and Ble Service

[omert08]

Issues fixed:

• The app was not compiling with Flutter 2, minSdkVersion is changed in Gradle file.
• Ble service was not working if BT is already enabled in Android.
• The app was giving NullParameter error for ble_peripheral in WiFi Bloc, there was no communication between BleBloc and WiFiBloc, it is solved.

Any plans to merge? Flutter 2 support would be a huge improvement.

I've tested this with my ESP32-WROOM-32D and works great on a range of Android devices and Apple devices.

Had some issues with image and crypto dependencies needing overrides.

image: ^3.0.0-nullsafety.0
crypto: ^3.0.0
