👋 I’ll get things started with a couple of thoughts:

• I know there are already quite a few examples, but some of them are a bit dated and could be improved or modernized. Are there particular examples you’d like to see refreshed, or new scenarios you’d like covered?
• Another question I have: would you prefer more focus on new features (like better Soroban support) or on developer experience improvements (updated docs, clearer error messages, etc.)?

I’d love to hear your perspective — even short replies like “yes, please update the examples for payments” are super useful. Don’t be shy, your input directly shapes where this SDK goes next. 🚀

Hi,

I'd like to build an app for web and mobile simultaneously, but currently I get a few errors when I try to run my app in a web browser.

The errors:

../../.pub-cache/hosted/pub.dev/stellar_flutter_sdk-2.2.1/lib/src/constants/bit_constants.dart:58:34:
Error: The integer literal 0xFFFFFFFFFFFFFFFF can't be represented exactly in JavaScript.
Try changing the literal to something that can be represented in JavaScript. In JavaScript 0x10000000000000000 is the nearest value that can be represented exactly.
static const int UINT64_MASK = 0xFFFFFFFFFFFFFFFF;
^^^^^^^^^^^^^^^^^^

../../.pub-cache/hosted/pub.dev/stellar_flutter_sdk-2.2.1/lib/src/soroban/contract_spec.dart:439:19:
Error: The integer literal 0x7FFFFFFFFFFFFFFF can't be represented exactly in JavaScript.
Try changing the literal to something that can be represented in JavaScript. In JavaScript 0x8000000000000000 is the nearest value that can be represented exactly.
if (intVal <= 0x7FFFFFFFFFFFFFFF) {
^^^^^^^^^^^^^^^^^^

../../.pub-cache/hosted/pub.dev/stellar_flutter_sdk-2.2.1/lib/src/soroban/contract_spec.dart:461:52:

if (intVal >= -0x8000000000000000 && intVal <= 0x7FFFFFFFFFFFFFFF) {
^^^^^^^^^^^^^^^^^^

Hi djr277,

thank you for your message.

The Flutter SDK offers supports for Android and iOS but not for Web. After the holiday season, I will investigate on what it takes to add web support, so that you don't get the errors any more when trying to build for web. There was an attempt to do this before, but it wasn't possible at the time, especially because of issues that relate to number precision.

Best regards
Christian

Hello @djr277,

we updated the SDK for full web support.

See: release 3.0.0.

Can you please test if the new version works for you?

Best regards
Christian
