1.轮播图Swiper设置圆角，在外层Container设置圆角无效

Container(
            margin: EdgeInsets.only(left: 10, top: 10, right: 10),
            height: 100,
            child: ClipRRect(
            //设置圆角  
              borderRadius: BorderRadius.circular(10),
              child: Swiper(
                itemBuilder: (BuildContext context, int index) {
                  return InkWell(
                    onTap: () {
                      print('点击图片');
                    },
                    child: CachedNetworkImage(
                      imageUrl: ('url'),
                      fit: BoxFit.cover,
                      placeholder: (context, url) =>
                          Image.asset('站位图',
                              fit: BoxFit.cover),
                      errorWidget: (context, url, error) =>
                          Image.asset('站位图',
                              fit: BoxFit.cover),
                    ),
                  );
                },
                itemCount: _bannerList!.length,
                controller: _swiperController,
                autoplay: true,
                pagination: new SwiperPagination(
                    builder: DotSwiperPaginationBuilder(
                      color: ff4d040404, //page默认颜色
                      activeColor: themeBackground,
                      size: 6,
                    )), //底部page
              ),
            ),
          );

Text文本溢出
文本出现中文＋数字的组合时 Text组件显示不全，可做以下处理

Characters('abc').join('\u{200B}');

Text(Characters('abc').join('\u{200B}')),
