Configure Target Language

The target language for translation is managed by AppBuilder. To set or retrieve the target language, refer to the demo:
// Set the target language for translation
AppBuilder.getInstance().translateConfig.setTargetLanguage('zh');
// Get the current target language for translation
final currentLanguage = AppBuilder.getInstance().translateConfig.targetLanguage;

Enable or Disable Text Message Translation

The MessageList widget includes a toggle for the Text Message Translation feature in its config parameter. By default, this feature is enabled (true). To disable it, set the value to false:
MessageList(
  config: ChatMessageListConfig(isSupportTranslate: false),
),
Note：
Only text messages and text-based reference or reply messages are supported. Images, voice, video, files, emojis, custom messages, and other formats are not supported for translation.
The maximum translation request rate is 5 times per second.
