title: react-hook-form useFieldArray with React-Native
body: <p>Is it possible to use ReactNative with useFieldArray from react-hook-form? I couldn't find any reference for that.</p>
  <p>I'm trying to use it but I can't get the output data from the TextInputs. It looks like the onChange is not working, I tried to use the onChange prop but still couldn't make it.</p>
  <p>Example:</p>
  <pre><code>  const {
      control,
      formState: {errors},
      register,
      getValues,
      handleSubmit,
    } = useForm({
      defaultValues: {
        playerNameInput: [{playerName: ''}, {playerName: ''}],
      },
    });
  
    const {fields, append, remove} = useFieldArray({
      control,
      name: 'playerNameInput',
    });
  return(
  &lt;&gt;
  {fields.map((player, index) =&gt; (
      &lt;View&gt;
          &lt;Controller
              control={control}
              rules={{required: true}}
              name=&quot;playerNameInput&quot;
              render={() =&gt; (
                  &lt;TextInput
                  style={{width: 100}}
                  defaultValue={`${player.playerName}`}
                  {...register(`playerNameInput.${index}.playerName`)}
                  /&gt;
              )}
          /&gt;
  &lt;/View&gt;)}
  
  &lt;Button onPress={handleSubmit(data =&gt; console.log(data))}&gt;
          Save Changes
  &lt;/Button&gt;
  &lt;/&gt;
  
  )
  </code></pre>
