lmt*_*tvt 6 gridview colors flutter
我在 flutter 中使用 gridview ,遇到一个问题,屏幕的背景颜色是黑色的,但是当我返回 gridview 时,单元格的背景颜色是白色的。我想更改单元格的背景颜色。我尝试将 gridview 移动到容器内并添加 Boxdecoration,但它不起作用,你能帮助我吗?有我的代码:
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Theme.of(context).backgroundColor,
body: Center(
child: Column(
children: <Widget>[
conseil(text, lien),
SizedBox(height: 20,),
Text("GAME PIN", style: TextStyle(fontSize: 40),),
Container(
padding: EdgeInsets.fromLTRB(30, 10, 30, 10),
decoration: BoxDecoration(
border: Border.all(width: 2.0, color: Color(0xffa8277b)),
borderRadius: BorderRadius.circular(15),
),
child: Text(id, style: TextStyle(fontSize: 30),)),
Expanded(
child: StreamBuilder<QuerySnapshot>(
stream: Firestore.instance
.collection('rooms')
.document(id)
.collection('users')
.snapshots(),
builder: (BuildContext context,
AsyncSnapshot<QuerySnapshot> snapshot) {
if (!snapshot.hasData)
return Text("Chargement....");
else {
return GridView.count(
crossAxisCount: 6,
children: snapshot.data.documents
.map((DocumentSnapshot document) {
return OvalPic(
document['photo'], document['couleur']);
}).toList());
}
},
),
),
button(mypink, 'COMMENCER', context),
SizedBox(height: 15,)
],
),
),
);

}
将它包裹在 a 中Container并添加color到它应该可以做到,
return Container(
color: Colors.black,
child: GridView.count(
crossAxisCount: 4,
children: snapshot.data.documents
.map((DocumentSnapshot document) {
return OvalPic(
document['photo'], document['couleur']);
}).toList()));
