initialValue property
final
An optional value to initialize the form field to, or null otherwise.
This is called value
in the DropdownButtonFormField constructor to be
consistent with DropdownButton.
The initialValue
affects the form field's state in two cases:
- When the form field is first built,
initialValue
determines the field's initial state. - When FormFieldState.reset is called (either directly or by calling
FormFieldState.reset), the form field is reset to this
initialValue
.
Implementation
final T? initialValue;
