I am currently working on a Flutter application that I want to classify using a tflite model. I updated the gradle file but the result still did not change. I am open to the ideas of people who have ideas or can give advice on the subject. Thank you.

enter image description here

build.gradle file of the code is below.

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

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new FileNotFoundException()("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 31

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }
    aaptOptions {
        noCompress 'tflite'
        noCompress 'lite'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.detection_of_sth"
        minSdkVersion 19
        targetSdkVersion 30
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }

Change the android/build.dradle

    buildscript {
        ext.kotlin_version = '1.6.21'
        repositories {
            google()
            jcenter()
        }
    
        dependencies {
            classpath 'com.android.tools.build:gradle:4.1.0'
            classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        }
    }
    
    allprojects {
        repositories {
            google()
            jcenter()
        }
    }
    
    rootProject.buildDir = '../build'
    subprojects {
        project.buildDir = "${rootProject.buildDir}/${project.name}"
        project.evaluationDependsOn(':app')
    }
    
    task clean(type: Delete) {
        delete rootProject.buildDir
    }

And change the app/build.gradle

        def localProperties = new Properties()
        def localPropertiesFile = rootProject.file('local.properties')
        if (localPropertiesFile.exists()) {
            localPropertiesFile.withReader('UTF-8') { reader ->
                localProperties.load(reader)
            }
        }
        
        def flutterRoot = localProperties.getProperty('flutter.sdk')
        if (flutterRoot == null) {
            throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
        }
        
        def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
        if (flutterVersionCode == null) {
            flutterVersionCode = '1'
        }
        
        def flutterVersionName = localProperties.getProperty('flutter.versionName')
        if (flutterVersionName == null) {
            flutterVersionName = '1.0'
        }
        
        apply plugin: 'com.android.application'
        apply plugin: 'kotlin-android'
        apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
        
        android {
            compileSdkVersion 32
        
            sourceSets {
                main.java.srcDirs += 'src/main/kotlin'
            }
        
            defaultConfig {
                // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
                applicationId "your app name"
                // 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 21
                targetSdkVersion 32
                versionCode flutterVersionCode.toInteger()
                versionName flutterVersionName
            }
        
            buildTypes {
                release {
                    // TODO: Add your own signing config for the release build.
                    // Signing with the debug keys for now, so `flutter run --release` works.
                    signingConfig signingConfigs.debug
                }
            }
            aaptOptions {
                noCompress 'tflite'
                noCompress 'lite'
            }
        }
        
        flutter {
            source '../..'
        }
        
        dependencies {
            implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
        }
