showCountdown to be shown only when field in focus

[sherikovic]

Hey,

I think it makes sense to either make showCountdown depend whether the field is focused or export the isFocusedState. Something similar to this would be great:

{showCountdown && maxLength && isFocusedState && (
  <Text style={countdown}>
    {maxLength - (value ? value.length : 0)} {countdownLabel}
  </Text>
)}
