Android

Attention when building release versions since OpenCV has been built for different CPUS we recommend running this command to build multiple APKs:

flutter build apk --split-per-abi --release

Change the minimum Android sdk version to 21 (or higher) in your android/app/build.gradle file.

minSdkVersion 21

    if (data['success'] == true) {
      XFile panorama = data['panorama'];
      print("Final image returned $panorama.toString()");
    } else {
      print("Final image failed");
    }
  },
  // Callback function called when the camera lens is changed
  onCameraChanged: (cameraKey) {
    print("Camera changed ${cameraKey.toString()}");
  },
  // Callback function called when capture progress is changed
  onProgressChanged: (newProgressPercentage) {
    debugPrint("'Panorama360': Progress changed: $newProgressPercentage");
  },
),

onCaptureEnded will return XFile or null

• XFile if the panorama has been captured successfully
• null if the panorama has failed
