NineGridView class - nine_grid_view library

Constructors

NineGridView({Key? key, double? width, double? height, double space = 3, double arcAngle = 0, int initIndex = 1, EdgeInsets padding = EdgeInsets.zero, EdgeInsets margin = EdgeInsets.zero, AlignmentGeometry? alignment, Color? color, Decoration? decoration, NineGridType type = NineGridType.weChat, required int itemCount, required IndexedWidgetBuilder itemBuilder, int? bigImageWidth, int? bigImageHeight, Image? bigImage, String? bigImageUrl}): create NineGridView. If you want to show a single big picture. It is recommended to use a medium-quality picture, because the original picture is too large and takes time to load. 单张大图建议使用中等质量图片，因为原图太大加载耗时。 you need input (bigImageWidth + bigImageHeight) or (bigImage + bigImageUrl).
