2 years ago Hey @savastekin,
A few questions:
-
Did you follow the Android instructions in the Readme, with attention to each step?
-
Please post your app/build.gradle file from within the /android platform folder of your Flutter project.
-
Are you running this on a true Android device? (It won't work on an emulator)
-
Which Android version are you using on the device you are testing with?
