## 🇺🇸 Internationalization
### Pre-defined
Due to the limited translation possibilities, we only provide a few pre-defined translations into the following languages:
* `en` - English 🇺🇸
* `pl` - Polish 🇵🇱

First import lang and use it as `translation` prop.
```ts
import { pl } from 'rn-emoji-keyboard';

// ...

translation={pl}
```
### 🏁 Own
There is possibility to pass own translation to library with the prop called `translation` like this
```ts
translation={{
  smileys_emotion: 'Smileys & Emotion',
  people_body: 'People & Body',
  animals_nature: 'Animals & Nature',
  food_drink: 'Food & Drink',
  travel_places: 'Travel & Places',
  activities: 'Activities',
  objects: 'Objects',
  symbols: 'Symbols',
  flags: 'Flags',
}}
```
*If you have written a translation into your language, we strongly encourage you to create a Pull Request and add your language to the package, following the example of other langs.*
