This talk was first held during Android Meetup São Paulo #66, that happened on February 5th, 2019, in São Paulo, Brazil.
I've talked about what's new on Material Design with Material Theming and Components, showed how to implement it on a project and had a demonstration with open source components in a live coding presentation.
The content is in pt-BR.
