Fixes attempted:

1. Tried changing minSdkVersion from 16 to 21.
2. In the app level build.gradle added multiDexEnabled true to defaultConfig and added dependency for androidx.multidex:multidex:2.0.1.
3. Updated settings.gradle to -->

include ':app'

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
include ":$name"
project(":$name").projectDir = pluginDirectory
}

4. Included firebase_core: ^0.4.5 in pubspec.yaml and did pub get

The errors still remain the same.
Experts, please advise.

I have the same issue exactly. Thought it was worth noting the Flutter code works fine on iOS.

Steps to reproduce: Install stable release of Flutter 1.17.4, Go through steps of codelab at [https://codelabs.developers.google.com/codelabs/flutter-firebase/ ] adding firebase to the default app.

Expected Result: App runs identically on iOS and Android
Actual Result: App runs on iOS, App fails to run on Android with error
Plugin project :firebase_core_web not found. Please update settings.gradle. Plugin project :firebase_auth_web not found. Please update settings.gradle.

duplicate of #2796

I thought about this and thought it was environmental and was able to get my app working by resolving inconsistencies in my android applicationID and package settings, (I had renamed it) and using the settings in #2796 - all working on 1.17.5 now. sorry for the noise.
