Flutter 抽屉背景图片

Aqi*_*rid 5 flutter flutter-layout flutter-appbar flutter-navigation flutter-image

我想知道我是否可以在 flutter app drawer header 中使用背景图像而不是颜色,有什么办法吗?

我可以自定义颜色,但我想知道是否有任何属性可以使用自定义图像更改颜色。

您可以在 DrawerHeader 中使用装饰将图像设置为抽屉标题

  return Scaffold(
      appBar: AppBar(title: Text(title)),
      body: Center(child: Text('some text')),
      drawer: Drawer(
        // Add a ListView to the drawer. This ensures the user can scroll
        // through the options in the drawer if there isn't enough vertical
        // space to fit everything.
        child: ListView(
          // Important: Remove any padding from the ListView.
          padding: EdgeInsets.zero,
          children: <Widget>[
            DrawerHeader(
              child: Text('Drawer Header'),
              decoration: BoxDecoration(
                color: Colors.blue,
                image: DecorationImage(
                  image: AssetImage("assets/gold.jpg"),
                     fit: BoxFit.cover)
              ),
            ),
            ListTile(
              title: Text('Item 1'),
              onTap: () {
                // Update the state of the app
                // ...
                // Then close the drawer
                Navigator.pop(context);
              },
            ),
            ListTile(
              title: Text('Item 2'),
              onTap: () {
                // Update the state of the app
                // ...
                // Then close the drawer
                Navigator.pop(context);
              },
            ),
          ],
        ),
      ),
    );
