getting cloud_firestore: 0.9.0 dependency breaks flutter app

Question

I've added the cloud_firestore: ^0.9.0 package to my new flutter project, so I created a new flutter project just for testing the Firebase package.

and got this error, after "package get", and starting the project.

Launching lib\main.dart on Android SDK built for x86 in debug mode...

2. Downloaded google-services.json after creating an account on the firebase website.

3. FLUTTERAPP/android/buld.grundle ive added this line of code

   classpath 'com.google.gms:google-services:4.2.0'

4. FLUTTERAPP/android/app/build.grundle at the end i've added this like of code

   apply plugin: 'com.google.gms.google-services'

started the app..

Solution 1

The problem [RE: Flutter how to fix The number of method references in a .dex file cannot exceed 64K.] can be fixed by changing the app/build.gradle minSdkVersion value from 16 to 21. I think this is the same problem as above (or related) as I was having, but with a different error message.

Solution 2

You should also add the dependencies for the Firebase SDKs you want to use.

Add implementation 'com.google.firebase:firebase-core:16.0.1' to your MY_APP/android/app/build.grandle files a dependancy section like below.

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-core:16.0.1'
}

apply plugin: 'com.google.gms.google-services'

Try to open and build your android specific folder on Android studio, Then you will get some more meaningful error message
