So, another library is worked. package:zxing_widget/

BarcodeWidget(
            DataMatrixPainter(
              compact: true,
              gs1Format: true,
              '0104111123005281215A&r293P2t1',
              foregroundColor: Colors.blue,
            ),
            size: Size(200, 200),
          ),

But without < compact: true > it not worked. If true, GS1 Datamatrix well done.
