[移动开发]flutter 本地和远程 图片组件

远程图片

方式一：

class HomeContent extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    // TODO: implement build
    return Center(
        child: Container(
          width: 90,
          height: 90,
          decoration: BoxDecoration(
            borderRadius: BorderRadius.circular(150), //图片弧度 大于150就是圆
            image: DecorationImage(
              image: NetworkImage(//引入线上图片
                "https://gimg2.baidu.com/image_search/src=http%3A%2F%2Fimg.jj20.com%2Fup%2Fallimg%2Ftp09%2F210611094Q512b-0-lp.jpg&refer=http%3A%2F%2Fimg.jj20.com&app=2002&size=f9999,10000&q=a80&n=0&g=0n&fmt=auto?sec=1651126196&t=8e12fb97f289d817e91662ce32ab48c6",
              ),
              fit: BoxFit.cover, //容器填充
            ),
          ),
    ));
  }
}

方式二：?

class HomeContent extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    // TODO: implement build
    return Center(
        child: Container(
      child: ClipOval(  //图片改成圆组件
        child: Image.network(
          "https://gimg2.baidu.com/image_search/src=http%3A%2F%2Fimg.daimg.com%2Fuploads%2Fallimg%2F140505%2F1-140505004P3.jpg&refer=http%3A%2F%2Fimg.daimg.com&app=2002&size=f9999,10000&q=a80&n=0&g=0n&fmt=auto?sec=1651127584&t=4cfc3445e9aade3171809fbe864956d9",
          width: 90,
          height: 90,
          fit: BoxFit.cover, //满容器填充
        ),
      ),
    ));
  }
}

引入本地图片

1.创建images 文件夹?

? ? 创建2.0x 3.0x 4.0x 的文件夹?

?2.pubspec.yaml配置文件夹

class HomeContent extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    // TODO: implement build
    return Center(
      child: Container(
        child: ClipOval(
          child: Image.asset(
            "images/a.jpg",//本地路径
            fit: BoxFit.cover,
            width: 90,
            height: 90,
          ),
        ),
      ),
    );
  }
}
