A month of Flutter: configure Firebase Auth for Sign in with Google on iOS

Originally published on bendyworks.com.

Yesterday I configured Sign in with Google on Android. Today is more of the same but in iOS land.

From the app directory I ran open ios/Runner.xcworkspace to open the iOS project in Xcode. Then in Xcode I selected "Runner" under "Project navigator" in the left sidebar followed by "Runner" under "Targets" in the main content area. Here I set "Bundle identifier" to app.birb.

update Bundle identifier in Xcode

Using the development Firebase project from yesterday, I added a new iOS app using the same bundle ID.

add iOS app to Firebase project

Firebase then prompted me to download a GoogleService-Info.plist file.

download iOS config file

Once downloaded, I dragged the plist file into the Xcode "project navigation" sidebar within the "Runner" directory next to Info.plist. By dragging it into Xcode, it gets registered for inclusion during builds. There isn't any sensitive information in the file but for an open source project it will need to be different for every developer so I'm adding it to .gitignore.

drag plist into Xcode

I then skipped step three "add Firebase SDK" and step four "add initialization code".

There is one important change to ios/Runner/Info.plist: configuring a CFBundleURLSchemes. The value can be copied from the GoogleServiceInfo.plist file. I would like to not hard code this but I currently don't have a better alternative.

<array>
  <dict>
    <key>CFBundleTypeRole</key>
    <string>Editor</string>
    <key>CFBundleURLSchemes</key>
    <array>
      <!-- Copied from GoogleServices-Info.plist key REVERSED_CLIENT_ID -->
      <string>com.googleusercontent.apps.483795507272-cavro2su6d78ldumt6003lo2krdrb2dd</string>
    </array>
  </dict>
</array>

Starting the app should give Firebase the all set signal.

adding Android app to Firebase project

And the Sign in with Google button still doesn't do anything but maybe tomorrow it really will.

Code changes

ERROR_INTERNAL_ERROR makes it sounds to me like a server error of some sort. Maybe try again later or from a different network connection.

 

thanks for reply ....
