Flutter with internationalized adapter automatically generated

1. Introduction

During the study of other people's projects, I suddenly discovered this solution and shared it specially. It turns out that flutter already has a set of mature internationalization generation functions. After the configuration is completed, you only need to write arb.The main steps are as follows

• 1. Create a new l10n.yaml file
• 2. Add and configure the required files
• 3. Change pubspec.yaml
• 4.flutter packages get
• 5. Use

1. Create a new l10n.yaml file

Add the following:

arb-dir: lib/l10n/arbtemplate-arb-file: app_en.arboutput-localization-file: app_localizations.dartnullable-getter: false

Analysis:

• arb-dir: directory where arb is located
• template-arb-file: the default arb file
• output-localization-file: export filename
• nullable-getter: get if the internationalized text is nullable

2. Add and configure required files

Create new files and folders as follows:

• lib* arb* app_en.arb* app_es.arb* l10n.dart under the project

Content of the app_en.arb file

{"@@locale": "en","appName": "Remarks","@appName": {"description": "Remarks"}}

@appName means to configure something, description means to add comments, app_es.arb can be obtained in the same way

l10n.dart The code is as follows: (Although there is an error in the imported content, don't worry about it)

import 'package:flutter/widgets.dart';import 'package:flutter_gen/gen_l10n/app_localizations.dart';export 'package:flutter_gen/gen_l10n/app_localizations.dart';extension AppLocalizationsX on BuildContext {AppLocalizations get l10n => AppLocalizations.of(this);}

3. Change pubspec.yaml

Add generateproperty

flutter:uses-material-design: true# Add this property generate: true

4. Run flutter packages get

After the operation is successful, you can generate the code for internationalization adaptation in the .dart_tool directory, and then re-check the code that reported the error before, it is normal

5. Use

MaterialApp is modified as follows:

Where to use:

There are many more contents of arb, such as adding parameters, etc., you can study it yourself, the above is over!
