I am developing a Flutter app, in which I need to show navigation to the user for a place. So, how can I open a map application from my Flutter app like we do using external
I think you are looking for a scenario where you want to open device installed app from Flutter?
If so , you can use a package called device_apps.
This FLutter package also shows you icon of app to display and you can open app by package name as well.
Just browse all methods it offers. I am using it for my Flutter FItness app to launch installed music player.
