如何在Flutter中选择并上传多张图片

dependencies:
  image_picker: ^0.8.4+4

import 'package:image_picker/image_picker.dart';

List<File> selectedImages = [];

void selectImages() async {
  List<XFile>? images = await ImagePicker().pickMultiImage();
  
  if (images != null) {
    selectedImages = images.map((image) => File(image.path)).toList();
  }
}

import 'package:cosdart/cosdart.dart';

void uploadImages() async {
  final String bucket = 'your-bucket-name';
  final String region = 'your-bucket-region';
  final String accessKey = 'your-access-key';
  final String secretKey = 'your-secret-key';

  final CosClient cos = CosClient(
    region: region,
    accessKey: accessKey,
    secretKey: secretKey,
  );

  for (int i = 0; i < selectedImages.length; i++) {
    final File image = selectedImages[i];
    final String objectKey = 'image_${DateTime.now().millisecondsSinceEpoch}_$i.jpg';

    await cos.putObject(
      bucket,
      objectKey,
      image.readAsBytesSync(),
      contentType: 'image/jpeg',
    );

    String imageUrl = 'https://${bucket}.cos.${region}.myqcloud.com/${objectKey}';
    print('Image uploaded successfully. URL: $imageUrl');
  }
}
