Thanks guys for help. From your suggestions i reached a solution like this.

new LayoutBuilder(
        builder:
            (BuildContext context, BoxConstraints viewportConstraints) {
          return SingleChildScrollView(
            child: ConstrainedBox(
              constraints:
                  BoxConstraints(minHeight: viewportConstraints.maxHeight),
              child: Column(children: [
             // remaining stuffs
              ]),
            ),
          );
        },
      )
