Duplicate class com.google.android.exoplayer2.ui.DownloadNotificationHelper
Fixed it by adding below line in /android/app/build.gradle
dependencies {
....
implementation ('com.google.android.exoplayer:exoplayer:2.17.0')
}

How can I fix this error.? Below are my build.gradle files:
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 flutter.compileSdkVersion compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } defaultConfig { // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html). applicationId "com.example.college_club" minSdkVersion 21 targetSdkVersion flutter.targetSdkVersion 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 } } } flutter { source '../..' } apply plugin: 'com.google.gms.google-services'
android\build.gradle:

Blundell about 2 yearsTry disabling jetifier. stackoverflow.com/questions/51680671/what-is-jetifier
-
Sanket Kumar about 2 years@Blundell tried, still same error
-
Blundell about 2 yearsHmm not sure how you can get a jettifier error if jettifying is turned off? :-) unless you are directly depending on two jettified libraries?
-
esentis about 2 yearsGetting exactly the same error after updating to Kotlin
'1.6.10'
. Have you found any solutions ?
-
Sanket Kumar about 2 yearsThanks, but it didn't work, still having the same error

shuster about 2 yearsIt didn't help :/

shuster about 2 yearsAdding this line solves the problem but in this case I have errors in Flutter with
assets_audio_player
package. -
esentis about 2 yearsHey @shuster that's unfortunate. Check this issue github.com/flutter/flutter/issues/100948 it may assist you.
-
shuster about 2 yearsIt's related my issue, thanks. But still it didn't solve my problem. I will move to another package.
