我将 PageView
用于查看寻呼机功能,并在每个页面上显示图像,并在每个页面上包含一些文本和按钮.因为我正在使用 Stack
小部件将视图放在彼此上,例如 Android
中的 Relative-layout
,但我的图像在第一页PageView
未设置为适合屏幕我已经尝试了以下解决方案,如下所示
1).第一个链接
2).第二个链接
但没有得到正确的解决方案,我已经尝试了下面的代码行,
I am using the PageView
for the view-pager functionality and showing the image on each page with contains some text and button on each page.
As I am using the Stack
widget for putting the view on one another like Relative-layout
in Android
, But My Image on the First Page of the PageView
is not set to fit on the screen
I have tried the below solution like below
1).First link
2). Second Link
But not getting the proper solution, I have tried the below lines of code for it,
class MyTutorialScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
// TODO: implement build
return Material(
child: PageIndicatorContainer(
pageView: PageView(
children: <Widget>[
Stack(
//////ON THIS SECTION I AM GETTIG PROBLEM
children: <Widget>[
Container(
/////// NEED THE SOLUTION ON THIS SECTION
color: Colors.yellow,
child: Image.asset('images/walkthrough_1.png',
fit: BoxFit.fitWidth),
),
Positioned(
top: 40.0,
right: 40.0,
child: InkWell(
onTap: () {
print("HERE IS I AM");
},
child: Text(
"SKIP",
style: TextStyle(color: Colors.white),
),
)),
Positioned(
bottom: 48.0,
left: 10.0,
right: 10.0,
child: Column(
children: <Widget>[
Padding(
padding: const EdgeInsets.all(16.0),
child: Text(
"Welcome",
style: TextStyle(
fontSize: 20.0,
color: Colors.white,
fontWeight: FontWeight.bold,
),
),
),
Padding(
padding: const EdgeInsets.all(16.0),
child: Text(
"To The Ravindra Kushwaha App.
One tap Club Destination !",
style: TextStyle(

textAlign: TextAlign.center),
),
],
),
)
],
),
Container(
color: Colors.yellow,
child: Image.asset('images/walkthrough_2.png', fit: BoxFit.cover),
),
Container(
color: Colors.blueAccent,
child: Image.asset('images/walkthrough_3.png', fit: BoxFit.cover),
)
],
),
length: 3,
align: IndicatorAlign.bottom,
indicatorSpace: 5.0,
indicatorColor: Colors.white,
indicatorSelectorColor: Colors.purpleAccent,
padding: EdgeInsets.all(10.0),
),
);
}
}
请检查我从上面的代码中得到的屏幕
