App requires Multidex support in flutter?-CodePudding

I'm getting this error while building my app in Flutter. it seems the problem that the multidex is not enabled even though I did everything needed to enable it. this the error

[!] App requires Multidex support
    Flutter multidex handling is disabled. If you wish to let the tool configure multidex, use the --mutidex flag.
Exception: Gradle task assembleDebug failed with exit code 1
Exited (sigterm)

I have already checked all of the solutions. enabled Multidex support and used the latest version:

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.harfanahApplication.harfanah"
        minSdkVersion 21
        targetSdkVersion 32
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
    }
.
.
.

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation("androidx.multidex:multidex:2.0.1")
}

I also added these to gradle.properies

org.gradle.jvmargs=-Xmx1536M
android.useAndroidX=true
android.enableJetifier=true

Still it is not working. any suggestions?

CodePudding user response：

Have you tried "flutter clean" and then rebuild? You can let the Flutter CLI tool do it for you with "flutter build --multidex".
