java.lang.IllegalArgumentException: Failed to find configured root that contains /data/data/**/cache/storage/CAPTURE-20210427_125521.jpg

I am developing a flutter app in which I'm using webview_flutter plugin. Now inside the webview I want upload a file from the device. The problem is when I try to select browse button to choose the files from my device (or use Camera directly), I get IllegalArgumentException.
I found other issues like this but it didn't solve my problem:
java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/Android/data/
Android: FileProvider IllegalArgumentException Failed to find configured root that contains /data/data/**/files/Videos/final.mp4
FileProvider - IllegalArgumentException: Failed to find configured root
Below is the code for the package I'm using:

Building an android camera application

Trying to create an android application to record video and capture images. I've followed the tutorials thus far with some success however I must have a lack of knowledge about the android sdk to not be able to get around this issue. No doubt I will feel stupid once someone figures this out but I'm here to learn in the end.
Here is the MainActivity.java
package example.myapplication;
import android.content.Context;
import android.content.pm.PackageManager;
import android.hardware.Camera;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
public MainActivity(Context context) {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}

A couple of things that need to be sorted:
Please remove all constructors from classes that extend Activity. - Activities do not work this way. Please look read how Activity Life cycle works.
Please add the CameraPreview activity to your manifest as well.

delete MainActivity constructor
public MainActivity(Context context) {
}
Please read carefully the stacktrace:
java.lang.RuntimeException: Unable to instantiate activity
ComponentInfo{example.myapplication/example.myapplication.MainActivity}:
java.lang.InstantiationException: can't instantiate class
example.myapplication.MainActivity; no empty constructor

You have created constructor in your Activity. Remove the constructor from your Activities and use the Lifecycle callbacks.
As per android guidelines you should not create constructor in the Activity classes since android OS creates object of Activity classes and it use the default empty constructor of the class to create object.

What my application does is, opens up the camera application via an intent. Then loads the image/bitmao into an imageview. Whenever i click the save_btn button it gives me this error. Could anybody tell me why and give me a solution? Thank you.

Just guessing but it seems you store taken image only for local variable
Bitmap image = decodeSampledBitmapFromFile(file.getAbsolutePath(), 1000, 700);
While later in the code you try to store image from class variable with the same name
image.compress(Bitmap.CompressFormat.PNG, 90, fos);

public void storeImage(Bitmap image) {
imageView.buildDrawingCache();
Bitmap bm_img = imageView.getDrawingCache();
File pictureFile = getOutputMediaFile();
if (pictureFile == null) {
Log.d(TAG,
"Error creating media file, check storage permissions: ");// e.getMessage());
return;
}
try {
FileOutputStream fos = new FileOutputStream(pictureFile);
bm_img.compress(Bitmap.CompressFormat.PNG, 90, fos);
fos.close();
