Solution

  • Maybe you can use a StatefulWidget that wraps your DataTable, you can define List<DataColumn> dataColumns; in your state. And every time you get your source data from API/calculations/or somewhere. You can fill this dataColumns list from source data and invoke setState.

    Let's say you fetch Column names form database and put it in a List<String> columnNames=['Name','Surname','Phone','Adress'];

    setState(() {
   dataColumns=columnNames.map((string)=>DataColumn(label: Text(string)).toList();   
 }); 
    

DataTable(
          columns: dataColumns,
          ////....
    
    )
