Flutter PRO tip #0: Open a dialog at startup

Sir is it possible open a list at startup instead of whole app.. just simple list pop up.. i don't know hot to implement.. please help me

Thank you thank you 🙏🏻

Thank you simple and powerful tutorial

Thank you for this! May i ask can i use "don't show this message again" in the dialog? Or use toggle button to show or hide it

And if I need to show the dialog when a variable changes but just once. How can I do that?
