Unable to load JDK7 types (annotations, java.nio.file.Path): no Java7 support added

[thechinkysight]

Platform (android, iOS or both) :

I am on Android only, so I don't know about IOS

Error:

I/SavedLocation(11367): -> savedLocation ->
W/System.err(11367): java.lang.NullPointerException: Attempt to read from field 'com.folioreader.Config com.jideguru.epub_viewer.ReaderConfig.config' on a null object reference
W/System.err(11367): 	at com.jideguru.epub_viewer.Reader$1.run(Reader.java:65)
W/System.err(11367): 	at java.lang.Thread.run(Thread.java:923)
W/Java7Support(11367): Unable to load JDK7 types (annotations, java.nio.file.Path): no Java7 support added

Describe in detail:

I am on epub_viewer: ^0.2.1 and I have a simple TextButton like this:

TextButton(
            onPressed: () async {
              await EpubViewer.openAsset('assets/4.epub');
            },
            child: Text('Clicke Me!'))

As you can see I am getting the 4.epub from assets. But I wasn't able to do so. When I click the TextButton, following error is thrown without crashing the app:

I/SavedLocation(11367): -> savedLocation ->
W/System.err(11367): java.lang.NullPointerException: Attempt to read from field 'com.folioreader.Config com.jideguru.epub_viewer.ReaderConfig.config' on a null object reference
