Description

This interface extends all options from AbstractControlOptions, plus some options unique to FormControl.

Properties

Property	Description
nonNullable?: boolean	Whether to use the initial value used to construct the FormControl as its default value as well. If this option is false or not provided, the default value of a FormControl is null. When a FormControl is reset without an explicit value, its value reverts to its default value.
initialValueIsDefault?: boolean	Deprecated Deprecated Use nonNullable instead.
