Can you help me what's wrong with my code? There is a difference with the code, because i'm connecting Flutter with Java so the code must like that. Thank you!

What is exception?

[ArvinCS]

I tried to get the error log, but it crashed without any log

[ArvinCS]

I'm sure session id etc aren't null. It crashed when show() method invoked

[bullheadandplato]

Without crash logs I cannot identify the issue

[ArvinCS]

Yeah me too :( I followed all the instruction step by step

[bullheadandplato]

Did you find the issue?
