Introduction:

As the Flutter ecosystem continues to grow, developers are constantly seeking efficient solutions to streamline various processes in their mobile applications. One critical aspect is handling file uploads, which can be complex and challenging, especially when dealing with large files and unstable network connections. Today, I excited to introduce you to resumable_upload, a powerful Flutter package that simplifies resumable file uploads, ensuring a smooth and reliable user experience.

Understanding the Challenge

Uploading large files over networks can be problematic due to potential disruptions, such as network timeouts or app crashes. Traditional file upload methods often require starting from scratch, resulting in wasted bandwidth and user frustration. To overcome this, developers need a resumable upload solution that enables file uploads to pick up from where they left off after an interruption.

resumable_upload is a cutting-edge Flutter package designed to tackle the challenges associated with file uploads, especially when handling large files or unreliable network connections. The package leverages the concept of resumable uploads, allowing the application to resume the upload process seamlessly without starting over in case of any disruptions.

Key Features and Benefits

Resumable Uploads: resumable_upload offers resumable file uploads, enabling the app to resume uploading from the last breakpoint in case of failure or network disruptions. This ensures efficient use of bandwidth and a smoother user experience.

1. Pause and Resume: Users can pause the upload process manually and resume it later. This feature comes in handy when dealing with large files that might take considerable time to upload fully.

2. Progress Tracking: Keep your users informed about the ongoing upload process with built-in progress tracking. Display intuitive progress indicators and ensure transparency throughout the upload.

3. Network Resilience: The package intelligently handles network interruptions, retries, and connection errors, ensuring a robust upload process even in challenging network conditions.

4. Customization Options: Developers can fine-tune various parameters to match their app’s requirements, such as setting the number of retries, defining the upload chunk size, and more.

Getting Started
To get started with resumable_upload, follow these simple steps:

- Add the package to your pubspec.yaml file:

`dependencies:
  resumable_upload: ^0.0.1`

- Import the package in your Dart code:

`import 'package:resumable_upload/resumable_upload.dart';`

- Initialize the uploader client and start uploading your files:

`final filePath = await filePathPicker();
final File file = File(filePath!);
const String accountName = '[ACCOUNT_NAME]';
const String containerName = '[CONTAINER_NAME]';
final String blobName = file.path.split('/').last;
const String sasToken = '[SAS-TOKEN]';
client = UploadClient(
        file: file,
        cache: _localCache,
        blobConfig: BlobConfig(
            accountName: accountName,
            containerName: containerName,
            blobName: blobName,
            sasToken: sasToken),
      );
      client!.uploadBlob(
        onProgress: (count, total, response) {
          final num = ((count / total) * 100).toInt().toString();
            process = '$num%';
        },
        onComplete: (path, response) {
            process = 'Completed';
        },
      );`
