My Flutter app uses Stripe for in-app purchases, but every charge fails right when payment is initiated. I need someone who knows the Stripe Flutter SDK inside out to track down the root cause, patch the code, and prove that payments go through smoothly in both Test and Live modes. Key points • Stripe is already integrated; the problem appears before processing even starts, so logging, token creation, or request signing may be at fault. • The fix should work on both Android and iOS builds without breaking any existing flows. What I expect when we’re done: 1. Diagnosis report explaining why the initiation call fails. 2. Updated Dart/Swift/Kotlin code or backend tweak that resolves the issue. 3. Successful end-to-end test payments demonstrated on a video call or share screen. 4. A brief change log so I can merge the patch into Git. If you have recent experience debugging Stripe in Flutter, this should be a quick win.
