国际本地化生成空套利模板

Question

我在 flutter 本地化中使用 intl 并且我创建了 AppLocalization class 如下：

import 'package:flutter/material.dart';
import 'package:intl/intl.dart';
import '../l10n/messages_all.dart';

class AppLocalization {
  static Future<AppLocalization> load(Locale locale) {
    final String name =
        locale.countryCode.isEmpty ? locale.languageCode : locale.toString();
    final String localeName = Intl.canonicalizedLocale(name);
    return initializeMessages(localeName).then((_) {
      Intl.defaultLocale = localeName;
      return AppLocalization();
    });
  }

  static AppLocalization of(BuildContext context) {
    return Localizations.of<AppLocalization>(context, AppLocalization);
  }

  // list of locales
  String get hello {
    return Intl.message('Hello',
        name: 'hello', desc: "Simple word for greeting ");
  }

}

class AppLocalizationDelegate extends LocalizationsDelegate<AppLocalization> {
  final Locale overriddenLocale;

  const AppLocalizationDelegate(this.overriddenLocale);

  @override
  bool isSupported(Locale locale) => ['en', 'ar'].contains(locale.languageCode);

  @override
  Future<AppLocalization> load(Locale locale) => AppLocalization.load(locale);

  @override
  bool shouldReload(LocalizationsDelegate<AppLocalization> old) => false;
}

然后运行这条命令生成intl_messages.arb模板

flutter pub run intl_translation:extract_to_arb --output-dir=lib/l10n 

lib/locale/app_localization.dart

它有时会使用这种格式成功生成 intl_messages.arb

{
  
  "@@last_modified": "2020-12-02T09:23:59.737528",
  "hello": "Hello",
  "@hello": {
    "description": "Simple word for greeting ",
    "type": "text",
    "placeholders": {}
  }
}

并且多次生成仅包含 last_modified 字段的空模板，终端中没有任何错误有什么问题？

虽然关键字相同，但此命令运行良好

flutter pub run intl_translation:extract_to_arb --output-dir=lib/l10n lib/locale/app_localization.dart

我想是因为这个没有在记事本中自动生成的新行 CR 和 LF 符号我使用记事本++并显示结束行符号来比较两个命令
