import 'package:chilkat/chilkat.dart';

void main() {
  // This requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final http = CkHttp();

  // Insert your AccessKey ID here:
  http.awsAccessKey = 'access-key';

  // Insert your AccessKey Secret here:
  http.awsSecretKey = 'secret-key';

  // To download from a bucket located in a different region, use the endpoint for that region, such as "oss-cn-hangzhou.aliyuncs.com 	"
  // See Alibaba Object Storage Service Regions and Endpoints
  http.awsEndpoint = 'oss-us-east-1.aliyuncs.com';

  final bucketName = 'chilkat';
  final objectName = 'seahorse.jpg';
  final localFilePath = 'qa_output/seahorse.jpg';

  try {
    http.s3DownloadFile(bucketName, objectName, localFilePath);
    print('File downloaded.');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
  }
