# KeyframeEffectReadOnly constructor Null safety

KeyframeEffectReadOnly(

1. Element? target,
2. Object? effect,
3. [Object? options]

)

## Implementation

    factory KeyframeEffectReadOnly(Element? target, Object? effect,
        [Object? options]) {
      if (options != null) {
        return KeyframeEffectReadOnly._create_1(target, effect, options);
      }
      return KeyframeEffectReadOnly._create_2(target, effect);
    }
