local_translation 0.0.1

On-device translation and language detection for Flutter.

local_translation

On device translation and language detection for Flutter.

iOS uses Apple's Translation and NaturalLanguage frameworks.

• isSupported() is true only on iOS 18+ physical devices. It is false on older iOS, the iOS Simulator.
• Translation may prompt the user to download language models.

Call isSupported() before translate or translateBatch. Language detection can still run when translation is unavailable.

Usage

final translation = LocalTranslation();

if (!await translation.isSupported()) {
  return;
}

final detection = await translation.detectLanguage('Hallo Welt');

final detections = await translation.detectLanguages([
  'Hallo Welt',
  'Guten Morgen',
]);

final one = await translation.translate(
  'Hallo Welt',
  targetLanguage: 'en',
);

final many = await translation.translateBatch(
  ['Hallo Welt', 'Wie geht es dir?'],
  sourceLanguage: 'de',
  targetLanguage: 'en',
);

sourceLanguage is optional. When omitted, the plugin auto detects.
