flutter ios app crashes after firebase setup

Question

I'm trying to configure firebase for my flutter ios app, I have downloaded my GoogleService-Info.plist and added it to the Runner/Runner folder in Xcode. When running the app, I get this error

Configuring the default Firebase app...
    "signalStrengthChanged:info:",
    "cellChanged:cell:",
    "connectionStateChanged:connection:dataConnectionStatusInfo:",
    "carrierBundleChange:"
)
    "signalStrengthChanged:info:",
    "cellChanged:cell:",
    "connectionStateChanged:connection:dataConnectionStatusInfo:",
    "carrierBundleChange:"
)
    "signalStrengthChanged:info:",
    "cellChanged:cell:",
    "connectionStateChanged:connection:dataConnectionStatusInfo:",
    "carrierBundleChange:"
)
    "signalStrengthChanged:info:",
    "cellChanged:cell:",
    "connectionStateChanged:connection:dataConnectionStatusInfo:",
    "carrierBundleChange:"
)
Configured the default Firebase app __FIRAPP_DEFAULT.

Any Ideas what I might be missing?

Answer 1

This issue is most likely due to missing content in the Info.plist, as it was for me.

Add the following to Info.plist

<key>GADApplicationIdentifier</key>
<string>ca-app-pub-3940256099942544~1458002511</string>

Be sure to replace ca-app-pub-3940256099942544~1458002511 with your AdMob ID.
