# isolate_worker
[](https://travis-ci.org/fluttervn/isolate_woker)
Library help run flutter tasks in other isolate. The library improve from original library: https://github.com/Dreckr/Worker
Improvement:
- Return callback progress for upload/download file
- Support cancel download/upload file
## Usage
Define class:
```dart
class DownloadTask implements FileTask> {
final Dio dio;
final String url;
final String savePath;
CancelToken cancelToken;
DownloadTask(
{@required this.dio, @required this.url, this.savePath, this.taskId});
@override
Future execute() {
return _doExecute();
}
Future _doExecute() async {
cancelToken = CancelToken();
var completer = Completer();
try {
final response = await dio.download(url, savePath,
cancelToken: cancelToken, onReceiveProgress: taskProgressCallback);
print('DownloadTask success: $response');
completer.complete(true);
} catch (e) {
print('DownloadTask error: $e');
completer.completeError(e);
}
return completer.future;
}
@override
ActionType actionType = ActionType.download;
@override
String taskId;
@override
var taskProgressCallback;
@override
void handleCancel(String taskId) {
cancelToken?.cancel('Cancel download $taskId');
}
}
```
Use:
```dart
Function(TransferProgress progress) progressCallback = (progress) {
setState(() {
percent = progress.count / progress.total;
});
};
var saveFolder = await Utils.getDownloadDirectory('Demo/Download');
final fullPath = '${saveFolder.path}/download.jpg';
final urlPath = 'https://sample-videos.com/img/Sample-jpg-image-2mb.jpg';
final dio = Dio();
var downloadTask = DownloadTask(
taskId: fullPath, dio: dio, url: urlPath, savePath: fullPath);
final worker = Worker(poolSize: 1);
await worker.handle(downloadTask, callback: progressCallback);
setState(() {
loading = false;
imagePath = fullPath;
});
```
