setErrors method
Sets errors on a control.
This is used when validations are run not automatically, but manually by the user.
Calling setErrors
will also update the validity of the parent control.
Usage
Control login = new Control("someLogin");
login.setErrors({
"notUnique": true
});
expect(login.valid).toEqual(false);
expect(login.errors).toEqual({"notUnique": true});
login.updateValue("someOtherLogin");
expect(login.valid).toEqual(true);
Implementation
void setErrors(Map<String, dynamic> errors, {bool emitEvent = true}) {
_errors = errors;
_status = _calculateStatus();
if (emitEvent) {
_statusChanges.add(_status!);
}
_parent?._updateControlsErrors();
// If a control's errors were specifically set then mark the control as
// changed.
markAsDirty(emitEvent: false);
}
