3 years ago This is the main part of the code
class WebViewExample extends StatefulWidget {
@override
WebViewExampleState createState() => WebViewExampleState();
}
class WebViewExampleState extends State<WebViewExample> {
@override
void initState() {
super.initState();
// Enable hybrid composition.
// if (Platform.isAndroid) WebView.platform = SurfaceAndroidWebView();
}
/// loadfinish()
void _webViewFinishLoadRequestCallback(String url) {
_progress=1.0;
if (mounted) {
setState(() {
//do sth
});
}
}
@override
Widget build(BuildContext context) {
return Material(
child: new Column(
children: <Widget>[
_linearProgressWidget(),
_body(),
// _webLogoutWidget(),
],
),
);
}
Widget _body() {
return new Expanded(
child: _webView(),
);
}
/// webView
Widget _webView() {
return Container(
child: WebView(
initialUrl: "https://www.baidu.com/",
javascriptMode: JavascriptMode.unrestricted,
onPageFinished: _webViewFinishLoadRequestCallback,
),
);
}
double _progress=0.45;
Widget _linearProgressWidget() {
if (1.0 == _progress) {
///if return Container(height:3.0); Crash would not happen;
return new Padding(padding: new EdgeInsets.only());
}
return new Container(
child: new LinearProgressIndicator(
backgroundColor: new Color(0x00FFFFFF),
value: _progress,
valueColor: new AlwaysStoppedAnimation<Color>(new Color(0xFF24C77E)),
),
height: 3.0,
);
}
}
Yesterday's experiment found that as long as there is no height change after initialization, it will not crash. This strange problem only appears on HuaWei Nova. Others of the same system will not have such problems.

3 years ago Can't reproduce this because I don't own a Huawei device mentioned above. The issue does not reproduce on my emulators and physical Xiaomi 5Plus device.

3 years ago This problem is not serious. I have no problem with other mobile phones except this one. Besides,It's hard to find HuaWei nova. It doesn't trigger as long as you don't change the height.
