Iterating through a list to render multiple widgets in Flutter?
Basically when you hit 'return' on a function the function will stop and will not continue your iteration, so what you need to do is put it all on a list and then add it as a children of a widget
you can do something like this:
Widget getTextWidgets(List<String> strings)
{
List<Widget> list = new List<Widget>();
for(var i = 0; i < strings.length; i++){
list.add(new Text(strings[i]));
}
return new Row(children: list);
}
or even better, you can use .map() operator and do something like this:
Widget getTextWidgets(List<String> strings)
{
return new Row(children: strings.map((item) => new Text(item)).toList());
}
It is now possible to achieve that in Flutter 1.5 and Dart 2.3 by using a for element in your collection.
var list = ["one", "two", "three", "four"];
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
for(var item in list ) Text(item)
],
),
This will display four Text widgets containing the items in the list.
NB. No braces around the for loop and no return keyword.
