I'm using the plugin fl_chart which allows to display some bars and when you tap them a popup is displayed. Example:

If the popup is big it will go outside the boundaries of the parent, for example if I have a card, the popup will be displayed over it:

Until here that is my expected behavior and is achieved with a code like this simplified for the question:

          Card(
            elevation: 8,
            shape:
                RoundedRectangleBorder(borderRadius: BorderRadius.circular(30)),
            child: Container(
              padding: const EdgeInsets.all(8),
              child: Row(
                  children: [
                     Expanded(
                        child: BarChart(
                              _getData(mySrc)
                          ),
                       ),
                     ),
                  ),

The number of bars that I will display is dynamic, therefore I want to make my row scrollable so I wrapped my row with a SingleChildScrollView:

                              child: Row(
                                children: [
                                  Expanded(
                                    child: SingleChildScrollView(
                                      scrollDirection: Axis.horizontal,
                                      child: SizedBox(
                                        width: 400,
                                        child: BarChart(
                                          _getData(mySrc),
                                        ),
                                      ),
                                    ),
                                  ),

And scrolling works as expected, but now it seems the popup is not allowed to go beyond the boundaries of the SingleChildScrollView:

Is there anyway I can keep the scrolling without damaging the popup generated by the fl_chart plugin?

try this

SingleChildScrollView(
    clipBehavior: Clip.none,

if it doesnt work you can try to set padding top to the SingleChildScrollView and make some extra space so popup doesnt get clipped
