[NirmalKumarYuvaraj]

Description

• In Android when changing the visibility of a WebView within a grid, Getting an issue where the elements underneath the grid start flickering.

Root Cause

• The flickering happened due to incorrect height handling. The use of MatchParent caused an infinite height, making the layout try to fill the entire parent height, which led to instability.

Resolution

• The infinite value was managed to prevent the layout from taking more space than necessary, ensuring stable behavior.
