Flutter for loop to generate list of widgets

You can try this :

@override
  Widget build(BuildContext context) {
    List<int> text = [1,2,3,4];
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Container(
        child: Column(
          children: [
            for ( var i in text ) Text(i.toString())
          ],
        ),
      ),
    );

Note that this was added with the updated of dart to version 2.3. You can read about some of the best changes in this article

Another method that was provided before dart 2.3 is this:

@override
  Widget build(BuildContext context) {
    List<int> text = [1,2,3,4];
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Container(
        child: Column(
          children: List.generate(text.length,(index){
            return Text(text[index].toString());
          }),
        ),
      ),
    );
