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:
FAILURE: Build completed with 2 failures.
1: Task failed with an exception.
Where: Build file 'C:\Users\okeyr\AppData\Local\Pub\Cache\hosted\pub.dev\flutter_tts-3.6.3\android\build.gradle' line: 31

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)

BUILD FAILED in 16s Exception: Gradle task assembleDebug failed with exit code 1
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?
