InputDatePickerFormField class

A TextFormField configured to accept and validate a date entered by the user.

The text entered into this field will be constrained to only allow digits and separators. When saved or submitted, the text will be parsed into a DateTime according to the ambient locale. If the input text doesn't parse into a date, the errorFormatText message will be displayed under the field.

firstDate, lastDate, and selectableDayPredicate provide constraints on what days are valid. If the input date isn't in the date range or doesn't pass the given predicate, then the errorInvalidText message will be displayed under the field.
