More examples are on the way... see awesome-opencv_dart and share yours

• compile libs for android, linux
• support for iOS, macOS
• add more examples
• documentation
• modify C wrapper to catch exceptions
• Native Assets, see native-assets branch
• async
• more/full test coverage
• directly include opencv source code, refactor cmakelists.txt
