Why do I get minsdk version compatability error in flutter for Android?

I am using Flutter and on android folder I ran ./gradlew clean build

But I get the following error:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':audio_session:processDebugAndroidTestManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [androidx.fragment:fragment:1.7.1] /Users/username/.gradle/caches/transforms-3/0f117a371f06cfd8b338874039e78472/transformed/fragment-1.7.1/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="androidx.fragment" to force usage (may lead to runtime failures)

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

See https://docs.gradle.org/7.6.3/userguide/command_line_interface.html#sec:command_line_warnings

My build.grade in the app level is as follows:

plugins {
    id "com.android.application"
    // START: FlutterFire Configuration
    id 'com.google.gms.google-services'
    // END: FlutterFire Configuration
    id "kotlin-android"
    // The Flutter Gradle Plugin must be applied after the Android and Kotlin Gradle plugins.
    id "dev.flutter.flutter-gradle-plugin"
}

def keystorePropertiesFile = rootProject.file('key.properties') // Correct path here
def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

def localProperties = new Properties()
def localPropertiesFile = rootProject.file("local.properties")
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader("UTF-8") { reader ->
        localProperties.load(reader)
    }
}

def flutterVersionCode = localProperties.getProperty("flutter.versionCode", "1") // Default to 1 if not found
def flutterVersionName = localProperties.getProperty("flutter.versionName", "1.0.0") // Default to 1.0.0 if not found

android {
    namespace = "app.tonns.trashcanfinder"
    compileSdk = flutter.compileSdkVersion
    ndkVersion = flutter.ndkVersion

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }

    defaultConfig {
        applicationId = "app.tonns.trashcanfinder"
        minSdk = 23
        targetSdk = flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger() // Use version code from local.properties
        versionName flutterVersionName // Use version name from local.properties
    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null

}

flutter {
    source = "../.."
}

When I click on the error link it’s as follows:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="androidx.fragment" >

    <uses-sdk android:minSdkVersion="19" />
</manifest>

Can someone please sugges how can I get rid of this error?
