Question

How can we add an event listener to see listen to events such as the appearance of a date picker?

In the below GIF, I want my keyboard to disappear whenever date time picker is visible.

I have keyboard listener function in my code but for this, I think I would need a function which listens when date time picker is shown

Here is how we are using tcomb-form-native

const Form = t.form.Form

const Gender = t.enums({
	M: 'Male',
	F: 'Female'
})

const options = {
	fields: {
		birthDate: {
			mode: 'date' // display the Date field as a DatePickerAndroid
		}
	}
}

const User = t.struct({
	email: t.String,
	username: t.String,
	fullName: t.String,
	gender: Gender,
	birthDate: t.Date,
	terms: t.Boolean
})

and then in my jsx

	<Form 
	  type={User} 
	  options={options} 
	 onChange={this.onChange} />

Also, If I can listen to the events, I can remove Tell us about yourself from the UI whenever picker is visible.
