Adding Cloud Firestore & Firebase to Flutter project (Android)

This is going to be a fairly long question, so I'll include a TL;DR at the end.

For days now, I've been trying to find a way to make my setup work, but to no avail. Now to make it complete and of aid to others, I'll be recording my steps here:

Steps to reproduce

Firebase instructions (as of now)

Install Google Repository (revision 58 currently) (not necessary anymore according to this issue, but done for verification).
Copy the package name found in android/app/src/main/AndroidManifest.xml. In my case this was com.omnisciamus.fire. Use it to create a new android app in the Firebase project along with a debug key.
Drop the created google-services.json in android/app
Modify the android/build.gradle and android/app/build.gradle. I've changed this to using the latest versions (modifications included below).
At this point I reran the compilation to see if any issues popped up already, and we have 3 of these warnings, which is most likely the google services plugin, not something I can change anything about: registerResGeneratingTask is deprecated, use registerGeneratedFolders(FileCollection)
Now we add the dependencies in the pubspec.yaml, also included below. Now there are several possible versions we can use, but I first tried the latest versions (by including a ^ in front of the versions).

Gradles

Changes to the android/build.gradle:

buildscript {
        repositories {
            google()
            jcenter()
        }

        dependencies {
            classpath 'com.android.tools.build:gradle:3.1.0' // upgraded from 3.0.1
            classpath 'com.google.gms:google-services:3.2.0' // added & upgraded from 3.1.1
        }
    }

And then we have the android/app/build.gradle:

//bottom of file
apply plugin: 'com.google.gms.google-services'

Pubspec

The dependencies structure of my pubspec looks like this:

dependencies:
  flutter:
    sdk: flutter
  cupertino_icons: ^0.1.0
  firebase_analytics: 0.3.0
  cloud_firestore: 0.3.1

Setup details

For additional details I've included my flutter doctor -v output:

Debug key

As this may become a tutorial I'll include a simple command to obtain the debug key (on Windows): cd %JAVA_HOME%\bin & keytool -exportcert -list -v -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

TL;DR

Cloud_firestore crashes with a version of 0.3.x, how do you fix this?

I also had similar issues while using firebase in flutter. I solved it by using this dependencies in my android/build.gradle file and remove any other existing dependencies.

classpath 'com.android.tools.build:gradle:3.1.2'
classpath 'com.google.gms:google-services:3.2.1'

and used this version for firestore and google in pubspec.yaml

cloud_firestore: 0.7.3

And if you have version related issues with any other firebase product then refer this link

I solved my current Cloud_Firestore problems by:

Changing the flutter channel from beta to master. Just run in the terminal flutter channel master. As proposed here Cloud Firestore 0.3.2 - Execution failed for task ...
worked with flutter dependencies: cloud_firestore: "^0.4.0" even cloud_firestore: "^0.3.2".

Hope this would help. I spent hours trying to figure it out why I could not compile my flutter app with cloud_firestore. I knew that the issue was around the flutter SDK versions, but I did not wanted to go for alpha. But the solution turned out to be as simple as using the master channel. Although, not sure yet what other issues may arise in the near future. However now, I can happily start testing with cloud firestore. ;)

For the Firebase plugins to work with Swift you need to use newer versions: But I am having android problems as well. I also tried switching flutter channel from beta to dev.

dependencies:
  flutter:
    sdk: flutter
  cloud_firestore: "^0.4.0"


  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.0

dev_dependencies:
 flutter_test:
    sdk: flutter
  image_picker: 0.4.1
  #google_sign_in: '>=2.1.0 '
  google_sign_in: '3.0.0'
  #firebase_analytics: '>=0.2.3'
  firebase_auth: '>=0.4.5'
  #firebase_auth: '>=0.5.3'        #not working on android
  #firebase_database: '>=0.3.5'   #works on android
  firebase_database: '0.4.2'      #works on android
  #firebase_storage: '>=0.1.4'    #not Working on android
  #firebase_storage: '0.2.0'       #not working on android
