DateFormatField takes in a required type this gives a date formating option for the textfield. The available types are:

type	example	description

type2	23/10/2022	This format uses a backslash (/) for separation and gives the date in full
type3	23-10-22	This format gives the last two digits of the year and uses a dash (-) for separation. It assumes the 21st century for all entries

Type 3

Type 4

basic example using type 4

DateFormatField(
    type: DateFormatType.type4,
    onComplete: (date){
        print(date.toString)
    }
)

Getting data

The onComplete call back function returns a Datetime nullable object containing the result from the DateFormatField.

The response from the call back returns null when ever the field is not complete but when the entry for the date input is complete, it returns true.

You can use a null check to update your value once the entry is complete. See the example below

DateFormatField(
    type: DateFormatType.type1,
    onComplete: (date){
        if(date != null){
            setState((){
                selectedDate = date!;
            });
        }
    }
)

removing calendar Icon

By default a calendar icon is attached as the trailling icon which triggers a Date Selection modal screen on clicking.

Calendar Icon on DateFormatField

Modal on clicking calendar Icon

Selecting a date prefills the DateFormatField using the selected date.

You can remove this icon by setting the addCalendar to false. this is shown in the example below:

DateFormatField(
    type: DateFormatType.type4,
    addCalendar: false,
    onComplete: (date) {
        print(date);
    },
),

Adding Decoration to DateFormatField

DateFormatField makes use of the default InputDecoration class which comes with Flutter TextFields. This allows you to style the textfield widget as much as you like. The example below shows this usage:

import 'package:date_format_field/date_format_field.dart';

DateFormatField(
    type: DateFormatType.type4,
    decoration: const InputDecoration(
        labelStyle: TextStyle(
        fontWeight: FontWeight.bold,
        fontSize: 18,
        fontStyle: FontStyle.italic,
        ),
        border: InputBorder.none,
        label: Text("Date"),
    ),
    onComplete: (date) {
        setState(() {
        _date = date;
        });
    },
),
