Please ensure you intialize your image asset in pubspec.yaml

  assets:
    - images/

and then call like

(
        height: 300,
        width: double.maxFinite,
        child: TabBarView(controller: _tabController, children: [
          ListView.builder(
            itemCount: 3,
            itemBuilder: (BuildContext context, int index) {
              return Container(
                width: 200,
                height: 300,
                decoration: BoxDecoration(
                  borderRadius: BorderRadius.circular(20),
                  color: Colors.white,
                  image: DecorationImage(
                    image: AssetImage(
                      "images/levender.jpg",
                    ),
                    fit: BoxFit.cover,
                  ),
                ),
              );

N.B: use commands flutter clean, flutter pub get and flutter run

It will happen sometimes. sometimes when you add an asset if this error happened just close your emulator and run it again and it will be ok.
