如何在Dart中从Json创建zip文件？

dependencies:
  archive: ^2.0.0

import 'package:archive/archive.dart';

var archive = Archive();

List<Map<String, dynamic>> jsonList = [
  {
    "filename": "file1.txt",
    "content": "This is file 1 content."
  },
  {
    "filename": "file2.txt",
    "content": "This is file 2 content."
  }
];

for (var json in jsonList) {
  var filename = json['filename'];
  var content = json['content'];

  var file = ArchiveFile(filename, content.length, content.codeUnits);
  archive.addFile(file);
}

var zipEncoder = ZipEncoder();
var zipFileBytes = zipEncoder.encode(archive);

import 'dart:io';

var zipFile = File('path/to/zipfile.zip');
var zipFileAccess = zipFile.openSync(mode: FileMode.write);
zipFileAccess.writeFromSync(zipFileBytes);
zipFileAccess.closeSync();
