Fluter build apk Failed-CodePudding

im trying to build a new android apk from flutter project, the minSdkVersion was 19 and the apk generated successfully, but not work on all android devices, some devices work with minSdkVersion 16, so when I changed the mindsVersion to 16 I cannot generate it cause I still get an error uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [com.google.firebase:firebase-core:20.0.0]

I'm trying to downgrade the Firebase Core but I cannot and still get this output.

here's my app/build.gradle

....
dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.google.firebase:firebase-analytics'
    implementation platform('com.google.firebase:firebase-bom:28.4.2')
}

apply plugin: 'com.google.gms.google-services'

and here's my android/gradle

buildscript {
ext.kotlin_version = '1.3.50'
repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:4.0.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.3.3'

}

}

can any one help me with this issue?

For me using minSdkVersion 26 is the sweet spot.

defaultConfig {
            applicationId "com.example.app"
            minSdkVersion 26
            targetSdkVersion 30
            versionCode flutterVersionCode.toInteger()
            versionName flutterVersionName
            multiDexEnabled true
}
dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:multidex:1.0.3'
    implementation "androidx.browser:browser:1.2.0"
    implementation platform('com.google.firebase:firebase-bom:29.0.0')
    implementation 'com.google.firebase:firebase-perf'
    implementation 'com.google.firebase:firebase-crashlytics'
    implementation 'com.google.firebase:firebase-analytics'
}

android/gradle

dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.8'
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.8.0'
        classpath 'com.google.firebase:perf-plugin:1.4.0'
}

You should downgrade flutter firebase_core too.
