Android Studio – Flutter errors when adding firebase auth and core

I am doing a chat application in flutter. I am only at the beginning, trying to set up Firebase with Flutter.

When I add to my pubspec.yaml: (copied from pub.dev)

firebase_auth: ^3.3.10
firebase_core: ^1.13.1

I get for both my Android and iOS simulators errors.
For android I have:

/Users/puskasimolaflora/AndroidStudioProjects/bsc/android/app/src/debug/AndroidManifest.xml Error:
    uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [com.google.firebase:firebase-analytics-ktx:20.1.0] /Users/puskasimolaflora/.gradle/caches/transforms-2/files-2.1/a328238d31bf521a00741e1d4b91c005/jetified-firebase-analytics-ktx-20.1.0/AndroidManifest.xml as the library might be using APIs not available in 16
    Suggestion: use a compatible library with a minSdk of at most 16,
        or increase this project's minSdk version to at least 19,
        or use tools:overrideLibrary="com.google.firebase.analytics.ktx" to force usage (may lead to runtime failures)

* What went wrong:

and for iOS I get:

CocoaPods could not find compatible versions for pod "firebase_auth":

    Specs satisfying the `firebase_auth (from `.symlinks/plugins/firebase_auth/ios`)` dependency were found, but they required a higher minimum deployment target.

I have already tried every solution I have found on these topics, still it is not running.

    for Android

    uses-sdk:minSdkVersion 16 cannot be… minSdk version to at least 19,

    in your build.gradle update your minsdk version to atleast 19

    This is assuming you added firebase android dependencies.

    in build.gradle

    //if you are using crashlytics
       classpath 'com.google.firebase:firebase-crashlytics-gradle:2.8.1'
//if you are using pref 
        classpath 'com.google.firebase:perf-plugin:1.4.0'
        classpath 'com.google.gms:google-services:4.3.10'

    in app/build.gradle

    dependencies {

...

implementation platform('com.google.firebase:firebase-bom:29.0.4')


    // Add the dependency for the Firebase SDK for Google Analytics
    // When using the BoM, don't specify versions in Firebase dependencies
    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.google.firebase:firebase-crashlytics'
    implementation 'com.google.firebase:firebase-perf'
}

    apply plugins

    apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.crashlytics'
apply plugin: 'com.google.firebase.firebase-perf'

    for IOS

    in your Podfile change platform version from 9 to a higher value eg platform :ios, '12.0' if commented dont forget to uncomment.

    If your build times are taking forever try using prebuilt firestore binary by adding this to your podfile

    pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '8.11.0'

    I faced the similar issue..
    when I changed minSDKVersion to 21 in app level build.gradle file, the problem resolved..
    Hope this helps..
