Question

In my application this error is occurring multiple time. How to avoid this?

I found some answers that say , its due to using multiple layer. But not clear with concept of multiple layer.

Answer 1

From the stack trace, it looks like you have a very deep widget nesting structure! That is the cause of the stack overflow, not so much the getChars. If you can, consider simplifying your widget tree, so widgets aren’t so deeply nested.
