maybeMix<V> static method

Prop<V>? maybeMix<V>(Mix<V>? value)

Creates a property from a nullable Mix value.

Returns null if value is null, otherwise calls Prop.mix. Preserves token references (MixRef objects) instead of wrapping them in MixSource.

Implementation

static Prop<V>? maybeMix<V>(Mix<V>? value) {
  if (value == null) return null;

  // Check if value is already a token reference (MixRef)
  // MixRef objects are Prop<V> instances with TokenSource that implement Mix interfaces
  // ignore: avoid-unrelated-type-assertions
  if (value is Prop<V>) {
    // ignore: avoid-unrelated-type-casts
    final prop = value as Prop<V>;
    if (prop.hasToken) {
      return prop; // Return token reference directly to preserve TokenSource
    }
  }

  return Prop.mix(value);
