我该如何处理动态列表 <DataColumn> 小部件，以避免Flutter DataTable小部件中的RenderFlex异常？

Question

I have a flutter DataTable (in a Container) that is constructed dynamically (values read from API).

Specifically, when it pulls in the columns it throws a RenderFlex exception. The same values used statically pose no problem.

Widget bodyData() => DataTable(
  columns: colWidgets, // set in setState() function 
  rows: rowWidgets // set in setState() function ,
);

...

colWidgets = ListofValues.map((value){
  return new DataColumn(
    label: Text(value)
  );
}).toList();

What is the best way to prepare the DataTable for these values via something like Padding or SingleScrollView?

Answer 1

I was able to solve this by moving the DataColumn widgets into a FittedBox widget within a Column widget. The key thing is that the parent/ancestor must have a flex property which the Column provides.
