🎯 New Feature Examples

Control the time picker to show only specific minute intervals (e.g., 15-minute increments):

`jsx
import DateTimePicker from '@ericboles/react-native-ui-datepicker';

export function AppointmentPicker() {
const [date, setDate] = useState();

return (
mode="single"
date={date}
onChange={({ date }) => setDate(date)}
timePicker
minuteInterval={15} // Only show :00, :15, :30, :45
/>
);
}

Perfect for birth year selection or any scenario where you only need a year:

`jsx
import DateTimePicker from '@ericboles/react-native-ui-datepicker';

export function BirthYearPicker() {
const [birthYear, setBirthYear] = useState();

return (
mode="single"
yearPickerOnly
startYear={1920}
endYear={new Date().getFullYear()}
onChange={({ date }) => {
// date is now just the year integer (e.g., 1984)
setBirthYear(date as number);
}}

}
`

Features:
- Returns just the year as an integer (e.g., 1984)

date={date}
onChange={({ date }) => setDate(date)}
timePicker
minuteInterval={15}
showViewPickerButtons
toggleHeaderLabel="Departure Time"
