[Bug] Gradle 8 support

[casper-rinnai]

flutter/flutter#125181

Flutter app android module can't be upgraded to gradle 8, until all dependencies which use native code are also upgraded or at least have namespace in app/build.gradle.

android {
namespace = "com.example.myapp"
...
}

Downgrade your build to gradle 7.

Only need to add the namespace for the module in the package for working with the newest requisites from gradle 8.x. Can do it manually until they fix it entering in the package and adding the namespace="de.mintware.barcode_scan"

I've do a temporaly fix

In the android/build.gradle change the android to

android {
    namespace "de.mintware.barcode_scan"
    compileSdkVersion 31

    compileOptions {
    sourceCompatibility JavaVersion.VERSION_17
    targetCompatibility JavaVersion.VERSION_17
}
kotlinOptions {
    jvmTarget = '17'
}

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
        main.proto.srcDirs += '../protos'
    }
    defaultConfig {
        minSdkVersion 18
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles 'proguard-rules.pro'
    }
    lintOptions {
        disable 'InvalidPackage'
    }
}

I will try later out of my work and run the tests. If I can build it with those parameters and got it fine, i do a pull request
