how you fix it. bro

[akash-flutterdev]

ok here is solution just add in android/app/build.gradle

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
shrinkResources false
minifyEnabled false
}
}

   shrinkResources false
    minifyEnabled false

See #772

[biner88]

In the proguard-rules file, add a line:
-keep class com.pauldemarco.flutter_blue.** { *; }

[spekary]
