There is a Box decoration used in the _ItemWidget. It will be nice to have this configurable. For example to use : https://api.flutter.dev/flutter/material/UnderlineTabIndicator-class.html. This way we can achieve much more configurability in the widget. Anyhow, thanks for creating this nice and very useful lib.

Emulator display overflow image when text field get focus because keyboard shows.
Wrap with SingleChildScrollView seems fix the problem

Thanks

Instead of appearing over/directly under the graph, the scrollbar appears on the bottom of the view as seen in the screenshot. Not sure if this also happens on Android.
