array<T> method

FormArray<T> array<T>(List<Object> value, [ List<ValidatorFunction> validators = const [], List<AsyncValidatorFunction> asyncValidators = const [] ])

Construct a new FormArray instance.

The value must not be null.

Can optionally provide a validators collection for the control.

Example:

Constructs an array of strings

final aliases = fb.array(['john', 'little john']);

Constructs an array of groups defined as Maps

final addressArray = fb.array([
  {'city': 'Sofia'},
  {'city': 'Havana'},
]);

Constructs an array of groups

final addressArray = fb.array([
  fb.group({'city': 'Sofia'}),
  fb.group({'city': 'Havana'}),
]);

Implementation

FormArray<T> array<T>(
  List<Object> value, [
  List<ValidatorFunction> validators = const [],
  List<AsyncValidatorFunction> asyncValidators = const [],
]) {
  return FormArray<T>(
    value.map<AbstractControl<T>>((v) {
      if (v is Map<String, Object>) {
        return group(v) as AbstractControl<T>;
      }
      if (v is AbstractControl<T>) {
        return v;
      }

      return control<T>(v as T);
    }).toList(),
    validators: validators,
    asyncValidators: asyncValidators,
  );
}
