How to iterate through widgets with different Views

Issue

Am beginner in flutter. I have four widgets with different view i.e. BarChart, LineChart, StackedBarChart and CircularChart. Then i created a List

 final List<Widget> widgetList = <Widget>[
    BarChartWidget(), LineChartWidget(), StackedBarChartWidget(), CircularChartWidget(),];

How can i iterate through List of this widgets in ListView

 body: new ListView.separated(
                itemCount: entries.length,
                padding: EdgeInsets.all(8.0),
                itemBuilder: (BuildContext context, int index) {
                  return Container(
                    height: 150,
                    color: Colors.amber[colorCodes[index]],
                    child: new widgetList[index],
                  );
                },
                separatorBuilder: (BuildContext context, int index) => const Divider(),
                )
                );

Solution

You were almost there. The issue is:

child: new widgetList[index],

That’s not a valid syntax. You cannot “new” widgetList, as it is a variable.

Just do:

child: widgetList[index],

Here’s the final syntax:

  new ListView.separated(
    itemCount: entries.length,
    padding: EdgeInsets.all(8.0),
    itemBuilder: (BuildContext context, int index) {
      return Container(
        height: 150,
        color: Colors.amber[colorCodes[index]],
        child: widgetList[index],
      );
    },
    separatorBuilder: (BuildContext context, int index) => const Divider(),
  );
