A scan code Flutter plugin, which is a Flutter package for HUAWEI ScanKit SDK.The HUAWEI ScanKit is a powerful library that is easy to use and fast to read.

Scan Kit automatically detects, magnifies, and recognizes barcodes from a distance, and is also able to scan a very small barcode in the same way. It works even in suboptimal situations, such as under dim lighting or when the barcode is reflective, dirty, blurry, or printed on a cylindrical surface. This leads to a high scanning success rate, and an improved user experience.

Scanning Barcodes

ScanKit supports 13 major barcode formats (listed as follows). If your app requires only some of the 13 formats, specify the desired formats to speed up barcode scanning.

  • 1D barcode formats: EAN-8, EAN-13, UPC-A, UPC-E, Codabar, Code 39, Code 93, Code 128, and ITF-14
  • 2D barcode formats: QR Code, Data Matrix, PDF417, and Aztec

Support camera scan code and local picture recognition.


  1. Configure Permissions
  2. Handling permission requests
  3. Calling APIs

Configure Permissions


Add the following to ios/Runner/Info.plist

    <string>Explain to the user here why you need the permission</string>
    <string>Explain to the user here why you need the permission</string>

Note that replacing the content of the tag gives the user a reason for needing the permission.

No configuration required for Android platform!

Permission Request

In Flutter, you need a plugin library for permission handling, here I recommend using another plugin library of mine: flutter_easy_permission, go here for detailed configuration.

Open the ios/Podfile file and add the following code:

target 'Runner' do
  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  # Add the library of permissions you need here
  pod 'LBXPermission/Camera'
  pod 'LBXPermission/Photo'

Then execute the command to install.

Calling APIs

  void initState() {
    scanKit = FlutterScankit()
	 ..addResultListen((val) {
	  // Back to the results
      debugPrint("scanning result:$val");

        onGranted: (requestCode, perms,perm) {
        onDenied: (requestCode, perms,perm, isPermanent) {});

Scan the code:

    // Request if no permission
    if (!await FlutterEasyPermission.has(perms: _permissions,permsGroup: _permissionGroup)) {
          FlutterEasyPermission.request(perms: _permissions,permsGroup: _permissionGroup);
    } else {
          // Call if you have permission
Future<void> startScan() async {
    try {
      await scanKit.startScan(scanTypes: [ScanTypes.ALL]);
    } on PlatformException {}
