CORS issue

[Adnan Vallippadan]

I am developing an application, which uses bitbucket APIs. My browser returns a CORS exception. How can I resolve that?
It was working before, The issue raised recently. 

When I searched for the issue, I can see several solutions saying for adding more header information. 
Unfortunately, It didn't solve my problem.
I've attached the screenshot, from my console.



I am using flutter for my web application development. Please help me to solve this.
