--------------------


### downloadModel(...)

```typescript
downloadModel(options: DownloadModel) => Promise<void>
```

Download a language model for offline translation.

Language models are around 30MB in size, so be sure to only download the models you need
and only download them using a WiFi connection unless the user has specified otherwise.

Only available on Android and iOS.

| Param         | Type                                                    |

### translate(...)

```typescript
translate(options: TranslateOptions) => Promise<TranslateResult>
```

Translate the given text.

If the language model for the given source and target languages is not downloaded,
