videoResolutionFromValue function

VideoResolution? videoResolutionFromValue(
  1. String value
)

由字符串反查枚举（接受简写）；无对应档位返回 null。

Implementation

VideoResolution? videoResolutionFromValue(String value) {
  final normalized = normalizeResolutionValue(value);
  for (final r in VideoResolution.values) {
    if (getVideoResolutionValue(r) == normalized) return r;
  }
  return null;
}
