Firebase – Updated : uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [:cloud_firestore]

android/app/build.gradle


    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "cmon.com"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-build-configuration.
        minSdkVersion flutter.minSdkVersion
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

Error:

G:FluttercmonandroidappsrcdebugAndroidManifest.xml Error:
    uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [:cloud_firestore] G:Fluttercmonbuildcloud_firestoreintermediatesmerged_manifestdebugAndroidManifest.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="io.flutter.plugins.firebase.firestore" to force usage (may lead to runtime failures)

FAILURE: Build failed with an exception.

How to modify the above given default versions. What is the reason for this error?

    You can manually add the minimum sdk version like this

    defaultConfig {
        applicationId "cmon.com"
        minSdkVersion 21
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

    In an Android Studio project, you have to edit the build.gradle file. In a flutter project, it is found at the path ./android/app/build.gradle.

    The parameter that needs to be changed in minSdkVersion is 19

    defaultConfig {
    applicationId "com.example.myapplication"
    //This is the part that needs to be changed, previously was 16
    minSdk 19 
    targetSdkVersion flutter.targetSdkVersion
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    vectorDrawables {
        useSupportLibrary true
    }
}

    Android SDK 16-18 is only a Best-effort platforms.
    Best-effort means supported through community testing, are platforms we believe we support through coding practices and ad-hoc testing, but rely on the community for testing.

    In your android/app/build.gradle flie,

    comment this line – minSdkVersion flutter.minSdkVersion
    and just add minSdkVersion 21 or flutter.minSdkVersion=21

    defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "com.example.phone_vrification"
    minSdkVersion 21
   // minSdkVersion flutter.minSdkVersion
    targetSdkVersion flutter.targetSdkVersion
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}
