My Flutter Android folder shows an error and I don't understand where the error is

There one pop up about Java that tell me to update it and I accidentally clicked on it. I am doing Geo location apps and after that, my Android folder got error, like this.
[C:\myapp\android\app\src\main\java\io\flutter\plugins\GeneratedPluginRegistrant.java:19: error: cannot access OnCompletionListener
flutterEngine.getPlugins().add(new com.baseflow.geolocator.GeolocatorPlugin());

Execution failed for task ':react-native-gesture-handler:compileDebugJavaWithJavac' with Android Studio Virtual Device

I can't setup properly what I am doing, let's explain as much as I can : I work with someone who started an Ignite project with the Andross package, I cloned the repo and tried to run the app using this tutorial, I did everything properly and was able to run my virtual device, but I had to chmod 777 my node_modules/ and my android/ for some reasons, and yet it won't work, I read here that i had to npm i jetifier but it didn't do much, tbh I have no idea what I'm doing, I really require help.
This is what I get when trying to react-native run-android :
react-native run-android
warn The following packages use deprecated "rnpm" config that will stop working from next release:
- react-native-vector-icons: https://github.com/oblador/react-native-vector-icons
Please notify their maintainers about it. You can find more details at https://github.com/react-native-community/cli/blob/master/docs/configuration.md#migration-guide.
error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually:
- react-native-device-info (to unlink run: "react-native unlink react-native-device-info")
- react-native-gesture-handler (to unlink run: "react-native unlink react-native-gesture-handler")
- react-native-i18n (to unlink run: "react-native unlink react-native-i18n")
- react-native-vector-icons (to unlink run: "react-native unlink react-native-vector-icons")
This is likely happening when upgrading React Native from below 0.60 to 0.60 or above. Going forward, you can unlink this dependency via "react-native unlink <dependency>" and it will be included in your app automatically. If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.

Latest version of react-native requires AndroidX. you have to jetify the project, until the maintainers updates their package, using:
npm install --save-dev jetifier && npx jetify
after that just
react-native run-android

Something wrong with compiling ionic project?

i have some problems with my ionic project.

I have got the same problem. As a workaround, you can configure a fix dependecy for the camera plugin.
in package.json:
"cordovaPlugins": [
...
"cordova-plugin-camera#2.3.0",
...

I think you may be used the wrong version of the plug-in.

4 Errors - error: package com.google.android.gms.appstate ETC

I'm fairly new to this and would like it if someone could like really dumb this down for me. I have been receiving these 4 errors constantly and its pretty frustrating.
I'm currently using Android Studio on a mac. These errors pop up when I try to create the build and I've tried searching online for this problem but this is what I found LINK and still did not help.

It seems that:
the package com.google.android.gms.appstate is not found. You haven't linked it to your program.
AppStateManager is not recognized, but it is the consequence of the first error.
