Flutter - Creating tables dynamically

_x000D_ _x000D_ I'm trying to dynamically create tables using Dart and Flutter. Something like this The number of table rows will change depending on the the JSON file passed in. I've read through and done all of the Flutter tutorials I can get my hands on and read through the Documentation on the Table and ListBuilder classes, but none of them quite accomplish what I'm trying to do, because the examples either only dynamically create single ListItems or all the data and/or Widgets are hard-coded. I've also tried doing this by doing: Table dynamicTable = new Table(); then dynamically adding children Widgets with dynamicTable.add(TableRow( children: [ Text("test1"), Text("test2"), Text("test3"), ] )); But I get an error saying "Cannot add to an unmodifiable list". Any tips on how to accomplish this would be greatly appreciated.

_x000D_ It's pretty easy, actually! All you have to do is, make a list of TableRows, and put that in the children parameter of your table. For example List tableRows = []; // dynamically make TableRows and add them to the list And then you can just do this: Table( children: tableRows, // other stuff )
