setup static method

dynamic setup()

初始化路径的环境

该方法用于设置应用程序的文件路径，包括数据库路径、图像路径、库路径和临时路径。 如果环境变量 FLUTTER_TEST 设置为 true，则使用 FLUTTER_TEST_HOME 环境变量作为库路径。 否则，根据平台类型（iOS、macOS、Android）获取相应的目录路径。

Implementation

static setup() async {
  if (loaded) return;

  if (Platform.environment['FLUTTER_TEST'] == "true") {
    String? home = Platform.environment['FLUTTER_TEST_HOME'];
    _library = home!;
  } else {
    if (Platform.isIOS || Platform.isMacOS) {
      var dir = await getLibraryDirectory();
      _library = dir.path;
    } else if (Platform.isAndroid) {
      var dir = await getApplicationDocumentsDirectory();
      _library = dir.path;
    }
  }

  _db = _library + '/storage.db';
  _image = _library + '/image/';
  _temp = _library + '/${Uuid().v4()}/';

  Directory imageDir = Directory(_image);
  await imageDir.create(recursive: true);

  loaded = true;
}
