flutter 隐藏返回按钮

Don't want to display that ugly back button ( :] ), and thus go for : AppBar(...,automaticallyImplyLeading: false,...);

Don't want the user to go back - replacing current view - and thus go for: Navigator.pushReplacementNamed(## your routename here ##);

Don't want the user to go back - replacing a certain view back in the stack - and thus use: Navigator.pushNamedAndRemoveUntil(## your routename here ##, f(Route<dynamic>)→bool); where f is a function returning truewhen meeting the last view you want to keep in the stack (right before the new one);

Don't want the user to go back - EVER - emptying completely the navigator stack with: Navigator.pushNamedAndRemoveUntil(context, ## your routename here ##, (_) => false);
