contentsize tabbarview

ContentSizeTabBarView #
A Flutter package that combines the functionalities of autoscale_tabbarview and expandable_page_view to provide a ContentSizeTabBarView widget. This widget allows you to create a tab bar view where each tab's height automatically adjusts to fit its content.

It uses autoscale_tabbarview to ensure smooth tab switching animation with the TabController and expandable_page_view to resize the tab bar view's content.
This package aims to address a specific use case where autoscale_tabbarview on release mode may not resize its content properly, especially when there is a GridView or similar widget inside it and the AutoScaleTabBarView itself is inside SingleChildScrollView/CustomScrollView.
It has been created to provide a solution to this issue while leveraging the strengths of the aforementioned packages.

Problem in autoscale_tabbarview package #
I have created the problem where autoscale_tabbarview fails, it is inside the example folder in this package repository. Just try to replace ContentSizeTabBarView with AutoScaleTabBarView in debug mode you will not see any problem but when you build apk and use that apk the problem will be visible. If you are not able to recreate the same problem create a issue and i'll help as much as i can.

Below image shows how autoscale_tabbarview behave when it is inside a CustomScrollView and it contains gridview on release.apk.
