Flutter如何从api下载pdf文件

import 'package:http/http.dart' as http;
import 'package:path_provider/path_provider.dart';
import 'dart:io';

Future<void> downloadPdfFromApi() async {
  // 发起网络请求
  var response = await http.get(Uri.parse('API_URL'));

  // 处理响应数据
  if (response.statusCode == 200) {
    // 获取文件存储路径
    var appDocDir = await getApplicationDocumentsDirectory();
    var filePath = '${appDocDir.path}/downloaded_file.pdf';

    // 保存文件
    File file = File(filePath);
    await file.writeAsBytes(response.bodyBytes);

    print('PDF文件下载完成，保存路径：$filePath');
  } else {
    print('请求失败：${response.statusCode}');
  }
}

void main() {
  downloadPdfFromApi();
}
