【问题描述】:
在列中添加行时出现错误。我收到以下错误:
I/flutter ( 6449): ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
I/flutter ( 6449): The following assertion was thrown during performLayout():
I/flutter ( 6449): BoxConstraints forces an infinite width.
I/flutter ( 6449): These invalid constraints were provided to RenderAnimatedOpacity's layout() function
我的代码也可供参考:
return new Scaffold(
backgroundColor: whiteColor,
body: new Column(
children: <Widget>[
imgHeader,
lblSignUp,
txtEmail,
Row(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
txtFirstName,
txtLastName
],
),
],
),
);
