The best thing about Flutter is that it's a product for everyone, and not simply a Google product. We can all participate and have a stake in its success since it is open source, whether by donating new code or documentation, developing packages that give the core framework new superpowers, authoring books and training courses that teach others, or assisting in the organization of events and user organizations.
