Flutter Flow have Firestore Section where you can link firestore Documents by defining proper data types

is there any way there to add a parameter as list of list
for example:

  List<List<double>> routePath = [];

I created a new DataType object as List
for example:
RouthPath -> with param routhPath of type List

and then add it in the parameter as List<Data(RouthPath)>

but I need something like

List< List < double > >
