analyze method

Future<PackageApi> analyze(ArgResults argResults, PreparedPackageRef preparedRef, { bool doAnalyzePlatformConstraints = true, bool doRemoveExample = true, })

Analyzes the given prepared Package ref. doMergeBaseClasses defines if base classes should be merged into derived ones. This allows to remove private base classes from the list of interface declarations. doAnalyzePlatformConstraints defines if the platform constraints of the package shall be analyzed.
