[required attention] Huge delay in showing purchase panel #24

Open iosephmagno opened 2 weeks ago

iosephmagno commented 2 weeks ago

Hello, we are under review form Apple and they noticed that purchase panel takes too much to show up.

 await purchaseSku(selectedPlan).then((transaction) { }

 // purchaseSku function
 static Future<GlassfyTransaction?> purchaseSku(GlassfySku sku) async {
    try {
      return await Glassfy.purchaseSku(sku);
    } catch (e) {
      return null;
    }
  }

When user taps the button we directly call Glassfy.purchaseSk() passing the sku, this methods that takes 3secs against a common delay of 300-900ms.

Probably there is a network delay caused by Glassfy servers or maybe delay with method.channel (since we noticed you communicate with native), can you please have a look? It has a bad impact on user experience and Apple doesn't like it.

Added loading animation to button to let you see delay

We also noticed that an earlier version of the plugin didn't suffer about this issue. In this video can be seen that purchase panel shows up almost instantly at 10:59 https://youtu.be/baIL-QCnkI0?si=Ld8msI8q2qCjjcwO&t=659 So, if it is not due to Sandbox test or Glassfy server delay, taking a look at latest changes to code should be helpful.
