This is my app level gradle file,

buildscript {
    repositories {
        google()
        jcenter()
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.3.0'
    classpath 'com.google.gms:google-services:4.2.0'
}

allprojects {
  repositories {
     google()
     jcenter()
}

This is the module level gradle file,

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
    implementation 'com.google.firebase:firebase-core:16.0.7'
}

The version of firestore package,

cloud_firestore: ^0.9.0

Is it a gardle issue or plugin issue?

Any suggestion is appreciated.

minSdkVersion 21 & targetSdkVersion 28 ?? You Still get same error after making the changes. ? — anmol.majhail, Feb 05 '19 at 04:57

Few Things:

Paste these lines at the end of gradle.properties file.

android.useAndroidX=true
android.enableJetifier=true

Changes in file app\build.gradle

android {
    compileSdkVersion 28

...

defaultConfig {
    minSdkVersion 21
    targetSdkVersion 28
    multiDexEnabled true
    ...
}

Go to terminal and launch command

flutter clean

then Build again.

As Mentioned in CHANGELOG of cloud_firestore 0.9.0:

0.9.0 # Breaking change. Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.

what made you to say that changing min sdk to 21 and target to 28? — chathura, Feb 05 '19 at 05:12
I read it somewhere on Flutter github issues.. plus its Latest Version - flutter further updates will add it too. stable channel has not being updated yet. — anmol.majhail, Feb 05 '19 at 05:18
