Try this:

{
  ( this.state.input === '' )  // ternary operator for checking condition
  ?
  this.props.value  // if condition satisfy
  :
  this.state.input  // if condition doesn't satisfy
}

The cleanest way would be

<Text>{this.props.input || this.props.value}</Text>

Which means if this.props.input is not a falsy value(including an empty string), it will render that, otherwise, it will render this.props.value.
