ListView inside FutureBuilder上的Flutter AnimatedContainer不起作用

FutureBuilder(
  future: fetchData(),
  builder: (context, snapshot) {
    if (snapshot.connectionState == ConnectionState.waiting) {
      return CircularProgressIndicator();
    } else if (snapshot.hasError) {
      return Text('Error: ${snapshot.error}');
    } else {
      return ListView.builder(
        itemCount: snapshot.data.length,
        itemBuilder: (context, index) {
          return AnimatedContainer(
            duration: Duration(seconds: 1),
            curve: Curves.easeInOut,
            height: _isSelected ? 100 : 50,
            color: _isSelected ? Colors.blue : Colors.red,
            child: ListTile(
              title: Text(snapshot.data[index]),
              onTap: () {
                setState(() {
                  _isSelected = !_isSelected;
                });
              },
            ),
          );
        },
      );
    }
  },
)
