Flutter Scroll View

I'm having problems making part of my web app scrollable. I have tried multiple solutions and none work. Any ideas?

Flexible(
          flex: 3,
          child: Align(
            alignment: Alignment.topRight,
            child: Padding(
              padding: const EdgeInsets.fromLTRB(20, 20, 0, 0),
              child: Column(
                children: [
                  Align(
                    alignment: Alignment.topLeft,
                    child: Text(
                        'Stories',
                        style: TextStyle(
                            color: Palette.white,
                            fontWeight: FontWeight.bold,
                            fontSize: 16
                        )
                    ),
                  ),
                  Stories(
                    currentUser: currentUser,
                    stories: stories,
                  ),
                  Padding(
                    padding: const EdgeInsets.fromLTRB(0, 20, 0, 20),
                    child: RecommendedCards(),
                  ),
                  Expanded(
                    child: Align(
                      alignment: Alignment.centerLeft,
                      child: RecommendedFollowingList(
                          users: recommendedFollow
                      ),
                    )
                  ),
                  PolicyView()
                ],
              ),
            ),
          ),
        ),

That's my code which I'm having trouble making scrollable.
