Install cuelinks SDK in your flutter app.

I am very new to App Development. An app was developed for my WordPress affiliate website using flutter template. But affiliate links are not working in Mobile App but working in Web Browser. After contacting CUELINKS AFFILIATE marketing they told me that they will work if you properly installing the given SDK in Android. https://cdn0.cuelinks.com/docs/Cuelinks+SDK+-+Integration+Guide.pdf

But my App is developed based on FLUTTER & i don't know how to & where to paste the code. If anyone in expert in FLUTTER APP. Plz message me.
