From vector_graphics_compiler:

   info • test/matrix_test.dart:78:17 • 'scaled' is deprecated and shouldn't be used. Use scaledByVector3, scaledByVector4, or scaledByDouble
          instead. Try replacing the use of the deprecated member with the replacement. • deprecated_member_use
   info • test/matrix_test.dart:81:53 • 'scaled' is deprecated and shouldn't be used. Use scaledByVector3, scaledByVector4, or scaledByDouble
          instead. Try replacing the use of the deprecated member with the replacement. • deprecated_member_use
   info • test/matrix_test.dart:92:17 • 'scaled' is deprecated and shouldn't be used. Use scaledByVector3, scaledByVector4, or scaledByDouble
          instead. Try replacing the use of the deprecated member with the replacement. • deprecated_member_use
   info • test/matrix_test.dart:107:15 • 'translate' is deprecated and shouldn't be used. Use translateByVector3, translateByVector4, or
          translateByDouble instead. Try replacing the use of the deprecated member with the replacement. • deprecated_member_use

These are test-only, but should be updated when feasible to avoid issues when they are eventually removed from vector_math.
