Question

I am getting the following errors in my flutter project and getting no clue how to resolve it error:

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

            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:multidex:2.0.1'
}
apply plugin: 'com.google.gms.google-services'

I have tried upgrading everything. also have tried solving it through existing available related answers but nothing worked for me. also checked that there are no two classes for protobuf. tried deleting build, .gradle files

Answer 1

ok so I resolved this issue if anyone is facing the same then you have to check the following

1. All the dependencies are updated
2. multiDexEnabled true

if above doesn't solve the issues then check if any dependency is repeated if you can't find any repeated dependency then try removing the dependencies one by one then run the application again it will take time but your application will run once the error causing dependency is removed

Thanks, Hope that it is useful
