Not working in android

[satvikreddy]

Issue1: Download link is incorrect

When running
dart run opencv_dart:setup android arm64-v8a

It tries to download: https://github.com/rainyl/opencv_dart/releases/download/v0.6.5/libopencv_dart-android-x64.tar.gz
But this link does not exist

I think expected link is: https://github.com/rainyl/opencv_dart/releases/download/v0.6.5/libopencv_dart-android-arm64-v8a.tar.gz

Issue2: flutter run failing on android (both emulator and real device)
I hardcoded the correct link and tried flutter run, after running the opencv_dart:setup command. Getting the following error.
Am i missing some step? After adding package I only ran opencv_dart:setup command (android arm64-v8a variation)

Code:

void main() {
  final img = cv.imread("assets/test.jpg", flags: cv.IMREAD_COLOR);
  final gray = cv.Mat.empty();

  cv.cvtColor(img, gray, cv.COLOR_BGR2GRAY);
  print("${img.rows}, ${img.cols}");

  cv.imwrite("test_cvtcolor.jpg", gray);

  runApp(MyApp());
}

My development device:

• Windows 11
• Flutter 3.16.9

look into IMPORTANT in README carefully, the correct command is

dart run opencv_dart:setup android --arch arm64-v8a

the default value of --arch(abbr: -a) depends on your desktop, i.e., most likely to be x64

I have tested on android simulator and arm64 device, it worked fine.

Thanks for the clarification. Working now!
