getAppDirectory static method

Implementation

static Future<Directory> getAppDirectory() async {
  Directory tempDir;
  //web 居然isMacos为true
  debugPrint(
      'Platform.isIOS=${Platform.isIOS},Platform.isMacOS=${Platform.isMacOS}, GeneralPlatform.isWeb=${Platform.isWindows}');
  if (Platform.isIOS || Platform.isMacOS) {

  }
  String tempPath = tempDir.path + "/";
  Directory file = new Directory(tempPath);
  if (!file.existsSync()) {
