• BREAKING ⚠️ (by @alikhavarii13) borderSide now is a named parameter (instead of a optional positional parameter in BarChartRodStackItem constructor. As it is a very minor breaking change, we decided to include it in this minor release (instead of doing a major release based on the semantic versioning. Sorry about that!
  So you just need to change this:

BarChartRodStackItem(
  0,
  10,
  Colors.green,
  BorderSide(color: Colors.white),
),

to this:

BarChartRodStackItem(
  0,
  10,
  Colors.green,
  borderSide: BorderSide(color: Colors.white),
),
