奥基做了一些更多的挖掘工作,我已经解决了这个问题。 基本上,“彩虹”文件略微过时。

首先,所生成的档案正在生成之中,但在>code><project_dir>dart_tools/flutter_gen/genl10n上重新编号。 发电机制作合成材料,自动提供给该项目,因此无需再添加<条码>。 变化。

第二,<代码>main.dart 必须考虑这一点:

import  package:flutter/material.dart ;
import  package:flutter_gen/gen_l10n/app_localizations.dart ;

class MyApp extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      localizationsDelegates: AppLocalizations.localizationsDelegates,
      supportedLocales: AppLocalizations.supportedLocales,
      title:  My app ,
      home: ... ,
    );
  }
}

Two things here:

1. The importing of the app_localizations.dart generated file (which the docs do mention but perhaps not explain well) and ...
2. Changing the localizationsDelegates and supportedLocales. You don t need to list all the delegates and locales mentioned in the docs as the generated localisation files automatically include them. Just switch to the two properties of AppLocalizations.

PS

在撰写上述著作后,我试图将上述标题国际化:

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      localizationsDelegates: AppLocalizations.localizationsDelegates,
      supportedLocales: AppLocalizations.supportedLocales,
      title: AppLocalizations.of(context).applicationTitle,
      home: ... ,
    );
  }

专题失败——原因是,在决定标题时,尚未确定代表和地方代表,因此从<代码>App Localizations.of(context)null. 相反,你们需要改写如下:

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      localizationsDelegates: AppLocalizations.localizationsDelegates,
      supportedLocales: AppLocalizations.supportedLocales,
      onGenerateTitle: (context) => AppLocalizations.of(context).applicationTitle,
      home: ... ,
    );
  }
```.  

`onGeneratedTitle` is called after the widget is setup which means localisation is available.

Addition to @drekka answer,

你们需要管理

flutter gen-l10n

如果不自动产生。

在需要时遇到类似问题,即通过国家扫盲委员会(CLI)在根本上(CLI)创建这些档案。

首先,应当有<代码>intl_utils作为项目依赖或在全球启动。

To install it as a dependency (and manage its version per project) - just add intl_utils: ^2.1.0 to the dependencies section of your pubspec.yaml (don t forget to set the version you need). After that, from the project directory run:

flutter gen-l10n --template-arb-file=intl_en.arb
flutter pub run intl_utils:generate

(change intl_en.arb to You actual .arb 如与缺省代码相匹配,则文档名称或表示整个参数。

To activate intl_utils globally (and use a single version of intl_utils on all your projects), do the following:

dart pub global activate intl_utils 2.1.0

然后从项目目录中管理:

flutter gen-l10n --template-arb-file=intl_en.arb
dart pub global run intl_utils:generate

就我而言,由于该项目的吨位尚未移至使用无效的安全性,加上<条码>intl_utils<>code>,由于项目依赖导致安全问题无效,因此在全球使用<条码>intl_utils 1.9.0。

Run this on your terminal or command-line:
dart pub global activate intl_utils 2.1.0
OR
dart pub global run intl_utils:generate

问题相同。 意外发现,我在<条码>lib上建立了10n.yaml,而不是基地 d。 Moved it should be, and all work!

如果在共和国内添加这一法典。 日元自动产生

flutter_intl:
  enabled: true
  class_name: AppLocalizations

http://www.ohchr.org。

经过一些研究,VsCode(就我的情况而言)似乎不见最近生成的<编码>申请-地点化.dart文档的更新。

www.un.org/Depts/DGACM/index_spanish.htm 为了解决这一问题,仅打开了这里的生成文件:。

.dart_tool/flutter_gen/gen_l10n/app_ localizations.dart

You should see your app_localizations.dart file updated

作为催复,在编辑<代码>.arb后,您需要发射flutter pub,以便作最新改动。

If you have the intl plugin in your code editor (Android Studio) then you should have this generated folder (lib/generated/l10n.dart).

在您的终端站内指挥这一指挥

flutter pub run intl_utils:generate

之后将开展工作。

At home, there was a connection problem, I have tools > Flutter > flutter upgrade

我也存在同样的问题,因为我从另一个开发商进口了该项目,没有一个解决办法帮助我。 在增加依赖性之后,你必须删除一切,并一劳永逸地启动该方案。 之后,该档案即立案。 只有到那时,你才能将档案输入该类别,并与之合作。

I had the same problem , I was using vs code, just restart vs code and everything will work just fine.

ERROR: Failed to generate localization files. type Null is not a subtype of type int of index pub finished with exit code 2
