Hide items in ListView.builder in Flutter-CodePudding

I would like to implement a filter in flutter and change dynamically the ListView based on the items that comply with the filters. I have a list of peoples (represented by the class People with attribute AGE in it). For instance I would like to show people with age < 18, but WITHOUTH REMOVING the items from the list generating the list view, just HIDE the items from the ListView that do not comply with the filter.

You only need to put a condition for rendering the list, and show the person only if he/she is < 18. you can do something like this in your listview:

ListView.builder(
  itemCount: items.length,
  itemBuilder: (context, index) {
    if (person.age < 18) 
      return Text(person.age);
    return Text('');
  },
)

Using Visibility Class from flutter sdk we can hide/show as we need
