openImagesPage function

void openImagesPage(
  1. NavigatorState navigatorState, {
  2. required List<String> imgUrls,
  3. List<String>? imgOriginalUrls,
  4. List<String>? heroTags,
  5. int index = 0,
  6. String? errorMsg,
  7. OnLongPressHandler? onLongPressHandler,
  8. OnPageChanged? onPageChanged,
})

打开多张图片 errorMsg 当图片加载错误时的描述信息 onPageChanged 切换图片时调用，第一次打开时也会被调用 返回的Widget可用于展示图片描述信息，如不需要可返回null imgOriginalUrls 原图 会最终加载此图
