Answer 1

If you want to add Widget dynamically,

  List<Widget> data() {
    List<Widget> list = List();
    //i<5, pass your dynamic limit as per your requirment 
    for (int i = 0; i < 5; i++) {
      list.add(Text("Index $i"));//add any Widget in place of Text("Index $i")
    }
    return list;// all widget added now retrun the list here 
  }

Now add this list into your column,

 Column(
    mainAxisSize: MainAxisSize.max,
    children: data(),
    ),

If you know beforehand which Widgets you want to add, you can use inline if statements when building the children:

Column(
     children: <Widget>[
     if(condition1)
      widget1,
     if(condition2)
     widget2,
_    weatherData,
],)

or if you do not know beforehand, you can call a function there that returns a List<Widget>.

Using the spread operator (...) you can even mix and match:

Column(
     children: <Widget>[
     if(condition1)
      widget1,
     if(condition2)
     widget2,
_    ..._getWeatherDataWidgets(),
],)

Hope this helps.
