//share image
File f =
    await ImagePicker.pickImage(source: ImageSource.gallery);
ShareExtend.share(f.path, "image");

//share video
File f = await ImagePicker.pickVideo(
        source: ImageSource.gallery);
ShareExtend.share(f.path, "video");

//share file
Directory dir = Platform.isAndroid
    ? await getExternalStorageDirectory()
    : await getApplicationDocumentsDirectory();
File testFile = new File("${dir.path}/flutter/test.txt");
if (!await testFile.exists()) {
  await testFile.create(recursive: true);
  testFile.writeAsStringSync("test for share documents file");

ShareExtend.share(testFile.path, "file");

///share multiple images
_shareMultipleImages() async {
  List<Asset> assetList = await MultiImagePicker.pickImages(maxImages: 5);
  var imageList = List<String>();
  for (var asset in assetList) {
    String path =
        await _writeByteToImageFile(await asset.getByteData(quality: 30));
    imageList.add(path);
  }
  ShareExtend.shareMultiple(imageList, "image",subject: "share muti image");
}

Future<String> _writeByteToImageFile(ByteData byteData) async {
  Directory dir = Platform.isAndroid
      ? await getExternalStorageDirectory()
      : await getApplicationDocumentsDirectory();
  File imageFile = new File(
      "${dir.path}/flutter/${DateTime.now().millisecondsSinceEpoch}.png");
  imageFile.createSync(recursive: true);
  imageFile.writeAsBytesSync(byteData.buffer.asUint8List(0));
  return imageFile.path;
