Attempt to invoke virtual method 'int android.content.Context.checkPermission'

[saurabhkumar8112]

Using v0.0.7 Platform Flutter v3.7.1

Unable to run exportImage. I have added the required permission in android_manifest.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I still get exception thrown from checkPermission module. Please have a look at the stack trace
