Description

Hello, Socket Mobile Team,
We are currently evaluating our upgrade path for our Flutter-based scanning application. We've seen the recent announcement regarding CaptureSDK 2.0 and its shift towards more reliable BLE workflows and the new dynamic framework architecture on iOS.
Since the current Flutter package (v1.5.60) still relies on the 1.9.x native iOS SDK, we are concerned about long-term parity and support for next-gen devices like the S721.

1. Is there an active development branch for Flutter 2.0?
2. When can we expect a release that bridges the new 2.0 native APIs?
   Maintaining a stable connection is critical for our users, and we’d love to take advantage of the 2.0 stability improvements as soon as they are available for Flutter.

Thanks!

Steps to Reproduce

N/A - This is a feature request (CaptureSDK 2.0 support), not a bug report.

Current behavior:

1. Use capturesdk_flutter: ^1.5.60 in pubspec.yaml
2. Run flutter pub get
3. Build iOS app → bundles CaptureSDK v1.9.139 (changelog confirms)

Expected Behavior

Expected: Flutter apps using capturesdk_flutter should bundle iOS CaptureSDK 2.0 (same as native iOS SDK), providing:

• New 2.0 architecture/stability improvements
• Latest BLE, SocketCam, NFC features
• Parity between Flutter and native iOS implementations

Current: Still bundles iOS CaptureSDK v1.9.139 despite 2.0 availability.

Actual Behavior

Actual: Flutter apps using capturesdk_flutter: ^1.5.60 bundle iOS CaptureSDK v1.9.139 (per changelog).

Confirmed by:

• pub.dev changelog: "Upgrade to iOS CaptureSDK v1.9.139"
• iOS framework inspection shows v1.9.x version, not 2.0

Hello @divyeshgohil85

thank you for submitting this feature request.

Indeed the plan is to release a new Flutter CaptureSDK including both iOS and Android CaptureSDK 2.0. And our first brand new Bluetooth LE barcode scanner S721 will be supported with this upcoming release.

We are about to release React Native 2.0 this week and then we will work on Flutter. As iOS and Android 2.0, some breaking changes will come along as the Bluetooth LE devices connection flow if you want to master this part into your app for more control with manual discovery, connecting and disconnecting a device.

We will keep you posted soon.

Hello @cyrille-socket

Thank you for the update.

Could you please share the expected release timeline for the Flutter CaptureSDK 2.0 with S721 support? This will help us plan our implementation.

Hello @divyeshgohil85

I'm sorry but we had to change our roadmap last minute and I have to release an iOS CaptureSDK version before making the Flutter one. So it will be fully compatible with the S721 in terms of properties supporting the S721 form factor like the stand configuration for instance. It will be released before Friday next week.

@cyrille-socket Thank you for the update!
Okay, so can I expect the new Flutter version by this Friday?

[cyrille-socket]

Hello @divyeshgohil85

yes this Friday it is!

[cyrille-socket]

Hello @divyeshgohil85,

here it is: https://github.com/SocketMobile/capturesdk_flutter/releases/tag/2.0.10

It supports our brand new Bluetooth LE scanner S721.

This version has some breaking changes as we migrated from 1.5 to 2.0. We have mainly introduced a new discovery flow where you can discover our scanners, connect and disconnect to them from your UI so you have the whole power on the connection flow. I advise you to look at the example app in this repo so you see how it works.

Let me know if you have any questions.

@cyrille-socket Thank you! I’ve updated to the latest version and it’s working fine. However, I have a few questions—could you please look into them?

We understand that a new discovery flow has been introduced, allowing us to discover scanners and connect or disconnect them directly from our app’s UI. This gives us full control over the connection flow.

• Does this mean that we no longer need the Socket Mobile Companion app to connect the reader, and that we can connect the scanner directly within our app without using the Companion app?
• Have you migrated the Socket Mobile iOS CaptureSDK from CocoaPods to the Swift Package Manager in this updated version?

Thank you!

[cyrille-socket]

Great to hear that it works!

1. You can still chose between using Companion and adding the scanners (Bluetooth Classic or LE) into it. Then you'll get the device arrival event as before. Or you can use the new API with add device, connect, disconnect to master your own connection flow in your app. It really depends on your needs.
2. Not yet. Cocoapods will be deprecated (read only from December 2026) so we will stop publish iOS CaptureSDK at this date (see this newsletter). And later this year we will transition to SPM in our Flutter SDK as well. Google already started to make it into Flutter but it's not stable or satisfying for us yet.
