Summary:
This PR makes sure that changing the `keyboardType` props of `<TextInput>` is reflected while the text field has focus. It is something that is also discusses in #13782. The workaround mentioned in that issue using `key` causes the TextInput to re-render itself which has some undesired side-effects.
Fixes#13782
```javascript
export default class KeyboardTypeApp extends Component {
state = { keyboardType: 'default' };
toggleKeyboardType = () => {
this.setState({
keyboardType: this.state.keyboardType === 'default' ? 'numeric' : 'default'
});
}
render() {
return (
<View style={{ padding: 40 }}>
<TextInput autoFocus value="Press Toggle :)" keyboardType={this.state.keyboardType} />
<Button title="Toggle" onPress={this.toggleKeyboardType} />
</View>
);
}
}
```
