Description:
implicitly animated list
Often, your lists represent some kind of data.
You can just pass the original list data to the ImplicitlyAnimatedList as
well as an itemBuilder for building a widget from one data point and it'll
animate whenever the data changes:
ImplicitlyAnimatedList(
// When you change items of this list and hot reload, the list animates.
itemData: [1, 2, 3, 4],
itemBuilder: (_, number) => ListTile(title: Text('$number')),
),

It works with all classes and works well with StreamBuilder:
class User {
String firstName;
String lastName;
// The ImplicitlyAnimatedList uses the == operator to compare items.
bool operator== (Object other) => other is User
&& firstName == other.firstName
&& lastName == other.lastName;
}
...
StreamBuilder<List<User>>(
stream: someSource.usersStream,
builder: (context, snapshot) {
if (!snapshot.hasData) {
return ...;
}
return ImplicitlyAnimatedList(
itemData: snapshot.data,
itemBuilder: (context, user) {
return ListTile(title: Text('${user.firstName} ${user.lastName}'));
}
);
}
),

Here's an example that generates random numbers and animates from one state to the next (notice it's only 10 fps because of being a gif):
