Flutter ListView Builder Dynamic Height

The ListView.builder widget in Flutter allows you to create a scrollable list of widgets based on an input List. To dynamically adjust the height of the ListView, you can take advantage of the ListView’s shrinkWrap property.

Here’s an example that demonstrates how to create a ListView.builder with dynamic height:


ListView.builder(
  shrinkWrap: true,
  itemCount: yourList.length,
  itemBuilder: (context, index) {
    return YourWidget(yourList[index]);
  },
)

In the code snippet above:

  • The shrinkWrap property is set to true, which tells the ListView to wrap its content tightly.
  • The itemCount is set to the length of yourList, which represents the number of items in the list you want to display.
  • The itemBuilder is a callback function that provides a context and an index. Inside this function, you can define the layout of each item in the list using YourWidget (replace this with your own widget).

Remember to replace “YourWidget” with your actual widget class that represents the item in your list.

By setting shrinkWrap to true, the ListView’s height will automatically adjust based on the height of its children. This allows the ListView to be scrollable within its parent container without overflowing or taking up unnecessary space.

Make sure to enclose the above code snippet within a proper Flutter widget hierarchy, such as a MaterialApp, Scaffold, or Container, to create a valid and runnable Flutter application.
