Flutter中syncfusion_flutter_charts在Android真机显示灰色屏幕问题
Android物理设备图表显示灰色屏幕,模拟器正常问题排查
我在Android模拟器中可正常绘制图表,但在Android物理设备上无法显示图表,仅呈现灰色屏幕。

相关代码如下:
@override Widget build(BuildContext context) { TextTheme _textTheme = Theme.of(context).textTheme; // TODO: implement build return SafeArea( child: Scaffold( backgroundColor: Colors.white, body: Column( children: [ SizedBox( height: 20, ), Padding( padding: const EdgeInsets.fromLTRB(20, 10, 20, 10), child: Row( children: [ GestureDetector( onTap: () { Navigator.pop(context); }, child: Icon( Icons.arrow_back_ios, color: Colors.blueAccent, size: 20, ), ), SizedBox( width: 10, ), Image.network( widget.cryptoData.cryptoImage!, height: 20, width: 20, // fit: BoxFit.fill, ), SizedBox( width: 6, ), Text(widget.cryptoData.cryptoName!, style: _textTheme.labelSmall), SizedBox( width: 2, ), Text('(' + widget.cryptoData.cryptoSymbol! + ')', style: _textTheme.titleMedium) ], ), ), SizedBox( height: 10, ), Padding( padding: const EdgeInsets.fromLTRB(20, 0, 20, 10), child: Row( children: [ Text( "\$" + limitDecimalToTwo( widget.cryptoData.cryptoValue.toString()), style: _textTheme.labelLarge), SizedBox( width: 20, ), Text( limitDecimalToTwo( widget.cryptoData.cryptoValueChange.toString()), style: TextStyle( color: widget.cryptoData.cryptoValueChange .toString()[0] == '-' ? Colors.red : Colors.green, fontSize: 14)), ], ), ), Expanded( flex: 4, child: Container( child: SfCartesianChart( primaryXAxis: CategoryAxis(), // primaryYAxis: CategoryAxis( // isVisible: false, // majorGridLines: const MajorGridLines(width: 0)), series: <ChartSeries<CryptoData, String>>[ LineSeries<CryptoData, String>( dataSource: cryptoDataList, xValueMapper: (CryptoData crypto, _) => getDateInProperFormat(crypto.date), yValueMapper: (CryptoData crypto, _) => crypto.value), ], ), )), SizedBox( height: 20, ), Padding( padding: const EdgeInsets.all(15), child: Expanded( flex: 2, child: CryptoRowWidget( cryptoName: widget.cryptoData.cryptoName, cryptoCode: widget.cryptoData.cryptoSymbol, cryptoImage: widget.cryptoData.cryptoImage, cryptoValue: widget.cryptoData.cryptoValue.toString(), cryptoValueChange: widget.cryptoData.cryptoValueChange.toString(), cryptoQunatityAvailable: '')), ), Padding( padding: const EdgeInsets.all(15), child: Expanded( flex: 1, child: Row( crossAxisAlignment: CrossAxisAlignment.center, mainAxisAlignment: MainAxisAlignment.center, children: [ ElevatedButton( style: ElevatedButton.styleFrom(shape: StadiumBorder()), onPressed: () { showAlertDialog(context, _textTheme, 'Buy'); }, child: Padding( padding: const EdgeInsets.fromLTRB(30, 10, 30, 10), child: Text( 'Buy', style: _textTheme.bodySmall, ))), SizedBox( width: 40, ), ElevatedButton( style: ElevatedButton.styleFrom(shape: StadiumBorder()), onPressed: () { showAlertDialog(context, _textTheme, 'Sell'); }, child: Padding( padding: const EdgeInsets.fromLTRB(30, 10, 30, 10), child: Text( 'Sell', style: _textTheme.bodySmall, ))), ], ), ), ) ], ), ), ); }
我曾找到过类似问题的解决方案,但该方案针对的是存在ListView父组件的场景,我的代码中没有ListView,因此无法适用,特此求助。
