setErrors method
Sets errors on a form control when running validations manually, rather than automatically.
If markAsDirty
is true or not set (default) then the control is marked
as dirty.
See dirty.
Implementation
void setErrors(Map<String, dynamic> errors, {bool markAsDirty = true}) {
_errors.clear();
_errors.addAll(errors);
_updateControlsErrors();
if (markAsDirty) {
this.markAsDirty(emitEvent: false);
}
}
