Flutter 文件选择器无法从 Android Gallery 获取 select 图像

Question

I am using file_picker 5.0.1 , while selecting image from Android device Gallery app it shows this error.

I/FilePickerDelegate(26740): User cancelled the picker request

This is the code snippet, I am using to call file picker

 FilePickerResult? result =
                            await  FilePicker.platform
                                .pickFiles(
                              type: FileType.image,
                                    allowMultiple: false,
                                    allowCompression: false,
                                    });
                            
                            if (result != null) {
                              print(result.files.length);


                            }

My flutter version: 3.0.5 Android compileSdkVersion: 31 Android minSdkVersion: 19 Android targetSdkVersion: 31

Answer 1

Check permission is granted and at least one album app is installed in the phone. Also you can try

FilePickerResult? result = await FilePicker.platform.pickFiles(
    type: FileType.custom,
    allowedExtensions: ['jpg', 'png'],
  );

or use this package https://pub.dev/packages/image_picker

This worked for me https://github.com/miguelpruivo/flutter_file_picker/issues/717#issuecomment-847801191

Updated my AndroidManifest.xml

Before

            android:launchMode="singleInstance"

After

            android:launchMode="singleTask"
