You will need to add the Google Maps package "com.google.android.apps.maps" in AndroidManifest.xml

<manifest package="com.your.package"> <queries> <package android:name="com.google.android.apps.maps" /> </queries> ... </manifest>

If you hadn't use google map apis then create one api key on GCP. After creating one api, use that in FLutter project.

I'm assuming you use this package google_maps_flutter As with all the flutter packages that imply connecting to some google api (or else), there is some setup involved that is described on the package page.

It is really important to do all that's needed before the package can work, including getting an api key Google Cloud, activating Maps for Android and for iOS on it (if you need both). And then you have some setup to do for both iOS and Android on your flutter app.

It's all described in the link I provided, and you should follow their instructions rigorously. All it takes is one little setup error to stop the whole thing from working.
