[agnihotritanisha]

Description : I am using xamarin.forms V5.0.0.2012 and xamarin.essential V1.6.1 . When editor area is small scrollview is not working inside editor in ios but it works fine in android . I have changed the version of xamarin.forms and xamarin.essential to latest but still I am having this issue in ios .

Steps to Reproduce

1. Added a dynamic editor , when keyboard is down editor is of max height and scrolling is working fine always
2. Then keyboard up the editor size is adjust according to keyboard size.
3. So in this case when editor height is small I am not able to view the one to two line text because scrolling is not working , when there is text of 6 to 7 line scrolling is working and I am able to see the text.

Expected Behavior: When editor height is small , I am able to see text and do scrolling also in ios

Actual Behavior: When editor height is small , I am not able to see text and not able to do scrolling also in ios

Basic Information : Have created dynamic editor by referring to this link -https://xamgirl.com/adjusting-elements-when-keyboard-shows-in-xamarin-forms/

Yes, I am creating a demo. Soon I will share with you.

Xamarin_Editor.zip This is our Demo Project.We are facing some problem with scrolling in editor when keyboard is up from so many days in our project. In our Demo project there is one line text so when the keyboard is up we are unable to scroll in editor. In this project for dynamic keyboard in Ios we have created a Custom Keyboard view renderer in our code inside the folder Renderer. In case of Android this is not creating a problem as when we keyboard up it automatically takes the cursor on the top of editor so our text is visible.
But in the case of IPhone the cursor reaches bottom of editor when keyboard is up so we are unable to see our text. In order to see our text when keyboard is up we are scrolling but the scrolls are not working in case of Ios. And can you please suggest us something so that our cursor reaches the top of editor and our text becomes visible in case of Ios just like android. And in case of android also when there is long text scrolling is not working.
