FlutterInappPurchase.buyProduct errors

[alamboley]

Hello,

Many thanks for this awesome plugin!

At the moment, I'm testing your plugin. I got an issue on this line var bought = await FlutterInappPurchase.buyProduct(product.productId);:

On Android:

@alamboley Thanks for the bug report. I cound't test from the actual purchase yet because I had some troubles with authenticating with my device. I'll look for this one this week!

@alamboley I've updated this quickly in version 0.2.3. You may try that one. Also, this still needs much more improvement currently. Maybe, it will take around 3 weeks to make this library stable to be released as version 1.

Thanks @dooboolab it's fixed! In the meantime, I tried getPurchaseHistory same problem. We can make all those return type as dynamic value, but in the long term we should have typed return.
I think the issue comes from unknow json key.

I will make more tests this afternoon, thanks!

@alamboley Thanks. I do think exactly as you do. Need more type enhancement. I will keep working on this until it gets quite stable. I've just released this quickly to get some contributors :)

[alamboley]

First PR ;) Congrats again for your hard work.

@alamboley Close this for now. Thank you for the PR.
