Flutter app build is failing, need help to resolve dependencies

Question

I am starting with flutter development and I thought that starting with opensource apps will be a good idea. I am trying to build this app : FlutterCinematic

and I am getting the following error:-

The current Dart SDK version is 2.1.0-dev.9.4.flutter-f9ebf21297.

Because movies_flutter depends on scoped_model >=0.1.1 <0.3.0 which requires SDK version <2.0.0, version solving failed.

pub upgrade failed (1)

I tried running flutter upgrade but it was not helpful. Any leads are appreciated.

Solution

Change in pubspec.yaml dependencies:

scoped_model: ">=0.1.1 <0.3.0"

to

scoped_model: ^1.0.0
