here with the Help of Row and Expanded widget you can achieve your UI. here is the example of that.

           Scaffold(
              body: Row(
                children: [
                  Expanded(
                    flex: 2,
                    child: ListView.builder(
                      itemBuilder: (context, index) {
                        return ListTile(
                          title: Text("$index"),
                        );
                      },
                    ),
                  ),
                  Expanded(
                    flex: 8,
                    child: ListView.builder(
                      itemBuilder: (context, index) {
                        return ListTile(
                          tileColor: index.isEven ? Colors.white : Colors.grey.withOpacity(0.1),
                          title: Text("$index"),
                        );
                      },
                    ),
                  ),
                ],
              ),
            )
