Flutter: Firestore component is not present

Question

I have a problem with Firestore database under Flutter. I have done everything, what the package setup documentation says, looked into 2-3 finished public application, and tried to use the package as others use. I even tried to implement native Firestore initialization, because i think the problem is on the platform side, but still, the application get

java.lang.NullPointerException: Firestore component is not present.

when i try to use the Firestore instance.

In project/build.gradle I set

classpath 'com.google.gms:google-services:4.0.1'

for dependency and also imported

'com.google.firebase:firebase-core:16.0.1'

'com.android.support:multidex:1.0.3'

I have the google-service.json in my app folder.

Can anyone help me with this problem? I wasted a day, and still nothing. Thanks a lot!

Answer 1

Okay, so I figured out from looking into an other problem.

I don't know if I was the only one who didn't know, but because of a new gradle update,

classpath 'com.google.gms:google-services:3.2.1'

was deprecated. I don't really know how the hell, but this caused, that somehow Flutter didn't get the instance right, and throw a nullPointer exception. If anyone has the same problem ( debug console show some deprecated warning), you should change the

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath 'com.google.gms:google-services:3.2.1'

     }
  }
}

lines in android/build.gradle to

buildscript {
    repositories {
            google()
            jcenter()
        }

    dependencies {
            classpath 'com.android.tools.build:gradle:3.3.0'
            classpath ('com.google.gms:google-services:3.2.1') {
                exclude group: 'com.google.guava', module: 'guava-jdk5'
       }
    }
}

I don't really know, why a deprecated form of dependency include caused such a problem, but this change worked for me, and I hope it helps others too. Besides that, I don't think this should cause such a wasted day, as a lot a of documentation should include this fix for the devs.

I also have the same issue after I update my cloud_functions package to 0.4.0. I tried out varies combination and I got this configuration working:

    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'
        classpath 'com.google.gms:google-services:4.2.0'
    }

Note that according to the official documentation , Flutter is currently compatible with version 3.2.1 of the Google Services Plugins. I did not do a full test based on 4.2.0 of the Google Services Plugins. So far, Firebase Authentication, Cloud Functions, and Firestore work fine.

Answer 4

Change the google-services to com.google.gms:google-services:3.2.1 . Although its an older version, works well with all the latest firebase extensions.

I came across this issue the other day I started working on flutter firebasebase realtime DB. Looks like it is some caching issue with flutter. After spending 50minutes to fix this issue, this comment helped me quickly resolve it.
