A Flutter package that implements the Instagram Bottom Navigation Bar by Yusuf Nadaroglu in Flutter.

Features

• x As in Instagram logic, when you save only 3 of the previous tabs and press the back button, it goes to the previous tab.
• x If you are in a tab, it will return to the old page when the back button is clicked.
• x If there is a tab you haven't been to before, that tab will be shown after you go.

Important Notes

• x The use of initState must be in state management so that the bottom bar pages are not loaded directly when the application is opened.
• x If you want the bottom navigation bar to stay fixed when you go to another page, set the rootNavigator parameter to false.

Navigator.of(context,rootNavigator: false).pushNamed(Routes.homePage);
