Error in running flutter project on using firebase messaging package - flutter

Question

While trying to run my Flutter project in Android Studio, I get the following error on using flutter package for firebase cloud messaging:
Launching lib\main.dart on ZUK Z2132 in debug mode...
Initializing gradle...
Resolving dependencies...
* Error running Gradle:
Exit code 1 from: C:\Users\Ada3\AndroidStudioProjects\fast_pos_tester\android\gradlew.bat
app:properties:
Configuration 'compile' in project ':app' is deprecated. Use 'implementation' instead.
FAILURE: Build failed with an exception.
* Where:
Finished with error: Please review your Gradle project setup in the android/ folder.
Build file 'C:\Users\Ada3\AndroidStudioProjects\fast_pos_tester\android\build.gradle'
line: 25
* What went wrong:
A problem occurred evaluating root project 'android'.
> A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:debugCompileClasspath'.
> More than one variant of project :firebase_messaging matches the consumer attributes:
- Configuration ':firebase_messaging:debugApiElements' variant android-aidl:
- Found artifactType 'android-aidl' but wasn't required.
here is the gradle code (within the app folder)
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.")
}

# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.io/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.io/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:

# - asset: fonts/TrajanPro_Bold.ttf

# For details regarding fonts from package dependencies,

I am not being able to figure out what's going on.

Answer 1

please check if you wrote the library dependencies/api keys correct
you need to post your flutter pubspec.yaml and gradle code so we can tell you what's wrong there :)

Answer 2

Try to run flutter clean and then flutter run. If it doesn't run, you should try adding this piece of code in android/build gradle: (you have to put the subprojects at the final of the file)
...
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'com.google.gms:google-services:3.2.0'
}
...
subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if(details.requested.group == 'com.android.support'
&& !details.requested.name.contains('multidex')) {
details.useVersion "26.1.0"
}
}
}
}
And in the android/app/build.gradle you should need this
dependencies {
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
