Could anyone help me to solve this problem?
Go to this folder and delete all cached files.
C:\Users\amabd.gradle\caches
Then try to restart the project.
I got the answer..
you should delete flutter SDK and reinstall it .then make the last update to it by:
flutter upgrade
I have the same problem after hours of searching and removing android studio. I downgraded java to java-8 and set java_home in OS and it worked like a charm.

I was building a flutter app in a Windows machine and I stopped working on it for several months, after that I now get issues on running the app. It shows those two errors:

Flutter doctor shows everything fine except:
[X] Visual Studio - develop for Windows
X Visual Studio not installed; this is necessary for Windows development.
Download at https://visualstudio.microsoft.com/downloads/.
Please install the "Desktop development with C++" workload, including all of its default components
But I don't think the issue is related with that.
I've I look in depth at failure number 1. I have check the file that gives the error and I found that in line 31:
apply plugin: 'kotlin-android'
So I just went to the file and deleted all the entries related with kotlin, because I am not using Kotlin (I guess).
Then if I rerun the app it now shows another error (related with tts again), but doesn't show the previous ones (not sure if I've moved forward or backwards)

After doing a search I found many people with that similar issue (even though none was related to tts plugin) which had adressed it with a flutter pub cache repair or a flutter clean. However, a flutter clean gives me no changes and error persists and when I have executed flutter pub cache repair it had shown:
Failed to repair flutter_tts 3.6.3. Error:
Pub failed to delete entry because it was in use by another process.
This may be caused by a virus scanner or having a file
in the directory open in another application.
Reinstalled 29 packages.
Failed to reinstall 1 package:
flutter_tts 3.6.3
pub finished with exit code 69
Now, if I rerun the code it gives me new error:
The plugin flutter_tts doesn't have a main class defined in C:\Users\okeyr\AppData\Local\Pub\Cache\hosted\pub.dev\flutter_tts-3.6.3\android\src\main\java\com\tundralabs\fluttertts\FlutterTtsPlugin.java or C:\Users\okeyr\AppData\Local\Pub\Cache\hosted\pub.dev\flutter_tts-3.6.3\android\src\main\kotlin\com\tundralabs\fluttertts\FlutterTtsPlugin.kt. This is likely to due to an incorrect androidPackage: com.tundralabs.fluttertts or mainClass entry in the plugin's pubspec.yaml.
If you are the author of this plugin, fix the androidPackage entry or move the main class to any of locations used above. Otherwise, please contact the author of this plugin and consider using a different plugin in the meanwhile.
This error also appears when running pub get or pug upgrade. But if I run pub outdated it gives me that:

I can't see any dependency related with tts.
Now here I am stucked in that error, I don't know how to proceed. If there is someone who could help me see the light I'd be grateful. Thanks in advance.
I am trying to run the code but it seems tts package is not well defined, anyone that could bring me some help?

I saw other people talk about this here but the solution that worked for them didn't work for me.
Here are the things I've tried:
./gralew clean or./gradlew build
/flutter clean
reinstalling flutter and android studio from scratch.
deleting the gradle files and the build files.
switching to another laptop.
I will be very grateful if you guys can help me.
Best Regards,
-Roee Hovav.
Peace!
Open Android Studio make sure you have the latest version installed, and everything is updated then go ahead and open the Flutter project and trying building it from Android Studio
I found the similar error but for me is missing of androidmanifest.xml and I have fixed it
For me I have deleted the android folder and run command "flutter create ."
then I got another of errors about "SdkMinVersion" and "Flutter multidex handling is disabled." and fixed it step by step
Anyway I have found this solution after I have fixed and hope it will help you
--> changing gradle version as the link below

if you run the first time it will download the grandle documentation. after that it wont take a long time
Just wait for some time, if you code is right , it will run on your Virtual Emulator soon. Android Studio does take time to load and personally lags on my PC if I am doing something simultaneously.
I recommend you to connect your personal device in Android Studio. It might give you quicker results.
Coming back to your error, does this help?

I use Ubuntu operating system and Android Studio as my IDE. please help
thanks in advance
Firstly your JDK version should be between 8 and 14 .
I solve this problem by going in the file
my_projet/android/gradle.properties
and put the command org.gradle.java.home=/path/to/jdk your version of the jdk should be between 8 and 14 , if jour jdk version is 14 it will not pass.
Because i am on Ubuntu OS i have written
eg: org.gradle.java.home=/usr/lib/jvm/java-11-openjdk-amd64
and after i run my project all works fine
I'm beginner for flutter. After coding something I want to simulate codes for Android emulator. I could run successfully a few days ago but today I can't. Error code says unable to find package java.lang. I didn't find where I should look for find problem. SDK path is correct, flutter doctor didn't find any problem. Also I can run project with iOS emulator. I am working on MacOS. Here whole error information.

You may want to run with verbose enabled, flutter run -v. Then you can find the possible error and warnings. It also happens when your code is incompatible to the gradle version. And the solution for it is to delete .gradle from your use home folder, then on next build flutter will redownload compatible gradle version. In case of Linux, rm -rf ~/.gradle.
Main problem is about packages. Some of them needs android migrate to androidx. When project migrated androidx, problem is solved.
