assimp.dart's Issues
Material color values should be returned as typed lists
While trying to load a model with materials, I found that assimp.dart
returns the material property values always as Floats or other single values.
For properties like colors the values should be returned as typed lists instead
so that all the value components can be accessed.
Currently in material.dart:85
the getter always returns just the first value pointed by the property pointer, even
when _property.mDataLength is larger than a single value.
As a suggested fix, the value getter should return a typed list when the data length is greater than a single value.
Tests are broken on Jammy
The tests are passing in the CI running 20.04. Focal has Assimp 5.0.1 whereas Jammy has 5.2.2. Was something fixed in Assimp that broke the tests generated with an earlier version of Assimp, or has there been a breaking ABI change?

Compability: Update dependencies
I can't use assimp.dart with the latest graphql-flutter version:
Because path_provider >=2.0.0 <2.0.8 depends on path_provider_windows ^2.0.0 and path_provider >=2.0.8 depends on path_provider_windows ^2.0.2, path_provider >=2.0.0 requires path_provider_windows ^2.0.0.
And because graphql_flutter >=5.0.0-beta.1 depends on path_provider ^2.0.1, graphql_flutter >=5.0.0-beta.1 requires path_provider_windows ^2.0.0.
And because path_provider_windows >=0.1.0-nullsafety.3 depends on ffi ^1.0.0 and assimp <0.1.0-dev.0 depends on ffi ^0.1.3, graphql_flutter >=5.0.0-beta.1 is incompatible with assimp <0.1.0-dev.0.
So, because syndb_client depends on both assimp ^0.0.6+1 and graphql_flutter 5.0.0, version solving failed.
