@nativescript-community/ui-material-bottom-navigation

Installation

Warning :warning: :warning:

From 5.x using material component will break N tab component on iOS (which is bound to be removed). This is needed to allow using the latest native iOS features. If needed you can use either bottomnavigationbar (this one is the best choice, closest to material design) or tabs (clone of N one, but with a little less features)

• tns plugin add @nativescript-community/ui-material-bottom-navigation

Be sure to run a new build after adding plugins to avoid any issues.
