PlatformException with release version

I'm seeing the following error in logcat when testing a release version of my APK. Everything works fine when the APK is a debug version.

Flutter version: v1.17.0
aws_s3 version: ^0.1.1+hotfix.5
Device: OnePlus 6, Android 10

Has anyone else experienced this? Happy to provide more information/code if necessary.

Usage:

Future<void> uploadVideo() async {
    final Directory extDir = await getApplicationDocumentsDirectory();
    final String filePath = '${extDir.path}/xxx.mp4';

    AwsS3 awsS3 = AwsS3(
      awsFolderPath: "xxx",
      file: File(filePath),
      fileNameWithExt: "xxx.mp4",
      poolId: "xxx",
      region: Regions.EU_WEST_1,
      bucketName: "xxx"
    );

      String result = await awsS3.uploadFile;
      debugPrint(result);
  }

Update to nulll safety

We are dependent on this plugin from sol long.
Now that the flutter 2.5 is released, please update this plugin to latest so we can move our projects to null safety too.

Uploading image to s3 using this plugin works fine in emulator but doesnot work in physical device

Failed to upload csv/json file to aws s3 through flutter app

So, I am developing an app using flutter sdk in android studio which will capture the motion sensor data and geolocator data. These data will be stored into a file (csv/ json/ bin) and that file will be uploaded into that specific bucket every 1 hour through my flutter app.

I have tried to upload data into S3 bucket using http class but this is not working. Again, everywhere there are many resources for uploading images. There are less resources for uploading file. I have also tried to use aws lambda but all tutorials are about uploading images.

Can anyone suggest me any way/tutorial/documentation about how can I upload files through my flutter to AWS S3 bucket? A code snippet is given below about how I am trying to upload data into s3 bucket.

` DatabaseHelper db = DatabaseHelper();

static const String _csvHeader = "Accelerometer, UserAccelerometer, Gyroscope, latitude-longitude\n";
List entries = [];

addEntry() async{
  var res = await db.queryGeoAll();  //to get all data of geolocator from database
  var geoCSV = mapListToCsv(res);    //converting them into a csv file
  entries.add("$accelerometer, $userAccelerometer, $gyroscope, $geoCSV");
}

clearEntries() {
  accelerometer= null;
  userAccelerometer= null;
  gyroscope= null;
  latitudeData= null;
  location = null;
  entries.clear();
}

void uploadSensor() async{
  String csvContent = entries.join("\n");
  print(csvContent);

  Uri uri = Uri.parse("Bucket Adress");
  http.MultipartRequest request = new http.MultipartRequest("POST", uri);
  request.files.add(new http.MultipartFile.fromString("csv", _csvHeader + csvContent));

  try {
    return await request.send().then((response) {
      if (response.statusCode == 200) {
        clearEntries();
        return true;
      } else {
        return false;
      }
    });
  } catch (e) {
    print(e.toString());
    //return false;
  }
}`

Here, I am getting an error like:
I/flutter ( 394): SocketException: Failed host lookup: 's3.us-east-1.aws.amazonaws.com' (OS Error: No address associated with hostname, errno = 7)
I have already added the following line to Android Manifest file
<uses-permission android:name="android.permission.INTERNET"/>

uploading_status result in out of box

Hi,
I'm using this plugins for upload file in s3 bucket, its working fine but there few issues that I found in my app with using this plugin,
1), Progress value goes to out of the box means percentage result in more than 100 (iOS only).
2) Initialisation of plugin take lots of time.
If any one have solution then please let me know.

Connection status of stream builder always remain waiting and always getting null value of progress so thats why my progress always remain 0

Android need set region when initialize AmazonS3Client

transferUtility1 = TransferUtility.builder().context(mContext).awsConfiguration(AWSMobileClient.getInstance().getConfiguration()).s3Client(new AmazonS3Client(credentialsProvider)).build();

I catch an error when upload in android device.
I guess, you might need set region of AmazonS3Client, could you please double check?

Result is always null.

What ever i upload, Result is always null. Doesn't throw any exception too..Hard to find where it went wrong. :(

Followed the example exactly.

AwsS3 awsS3 = AwsS3(
awsFolderPath: "your aws folder path",
file: "file is of type File",
fileNameWithExt: "file name",
poolId: "your aws pool id",
region: "your region using enum Regions",
bucketName: "your bucket name to upload");

Have added "in manifest also...

AWS upload is working fine when i tried with other plugins.. But i badly need to get progress of upload.

Doubted param is "awsFolderPath". Is there any specific format for providing it ?

Please help me out...Thanks

Reply already submitted exception in method channel

I'm using another method channel to show a notification in the android side when the upload begin and finish. When I upload 2 files simultaneously I'm getting an exception like this. I couldn't use the result on my method channel.

Access Denied (Service: Amazon S3; Status Code: 403) though Cognito pool ID

I used cognito pool ID, but when I try to upload a file to s3,
onError: com.amazonaws.services.s3.model.AmazonS3Exception: Access Denied (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied

In native Android app, the same cognito pool id can upload any file to s3 is ok.

Issue with deleting files in s3

Is there any way to delete once uploaded file from s3 bucket?

Release App Crash - Reply already submitted

Parameter in exception message

On uploading process I got this error:

onError: com.amazonaws.services.cognitoidentity.model.InvalidIdentityPoolConfigurationException: Invalid identity pool configuration. Check assigned IAM roles for this pool. (Service: AmazonCognitoIdentity; Status Code: 400; Error Code: InvalidIdentityPoolConfigurationException; Request ID: e35928a5-0370-4ebd-9845-f56d249f282e)

In that message the 'Request ID' does not match to the pool ID that I entered which starts with 'ap-northeast-...'
Does the plug-in use the pool ID input correctly? then what is the request ID in the error message?
