void setError(String fieldName, String? error)

• fieldName The name of the field to set the error for.
• error The error message to set for the field.

Implementation

void setError(String fieldName, String? error) {
  final field = state.get(fieldName);
  state.fields[fieldName] = field.updateError(error);
  var status = state.status;
  if (error != null) {
    status = BondFormStateStatus.invalid;
  } else if (state.status == BondFormStateStatus.invalid ||
      state.status == BondFormStateStatus.pristine) {
    // Only promote to valid if all fields are now valid
    status = _allValid(false)
        ? BondFormStateStatus.valid
        : BondFormStateStatus.invalid;
  }
  state = state.copyWith(
    fields: Map.from(state.fields),
    status: status,
  );
}
