iOS Rive initialization crash: init -> rive_text_ffi not found

Description

On iOS my rive animations are failing on initialization.

On Android this is working as expected.

Hi @julianfalcionelli, is this failing for you locally?

• Which version of Flutter are you using?
• What device is this reproducing on?

Can you try running flutter clean and rebuilding.

You can also try initializing Rive earlier in your app lifecycle. For example, at the start of main:

void main() {
  /// Initialize Rive's text, audio, and layout engines.
  /// This will automatically be called the first time a RiveFile is loaded if
  /// it has not been initialized. And does not need to be called.
  ///
  /// However, calling it early here makes the first
  /// visible Rive graphic load faster.
  unawaited(RiveFile.initialize());

...
  }

Hi @HayesGordon , thanks for your reply.

My Flutter version is:

Flutter 3.24.3 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 2663184aa7 (9 weeks ago) • 2024-09-11 16:27:48 -0500
Engine • revision 36335019a8
Tools • Dart 3.5.3 • DevTools 2.37.3

We can reproduce this in all the iOS devices we have (I can get you the list of models and iOS versions next week since I have to contact QA), for me I am testing on an iPhone SE and emulator (iPhone 15 Pro - iOS 17).

I tried by cleaning everything and rebuilding (flutter clean).

I also tried calling the RiveFile.initialize() as you said but I got the same error when calling that function:

flutter: Invalid argument(s): Failed to lookup symbol 'init': dlsym(RTLD_DEFAULT, init): symbol not found
flutter: 
#0      DynamicLibrary.lookup (dart:ffi-patch/ffi_dynamic_library_patch.dart:33:70)
#1      init (package:rive_common/src/rive_text_ffi.dart:497:16)
#2      init (package:rive_common/src/rive_text_ffi.dart)
#3      initFont (package:rive_common/src/rive_text_ffi.dart:814:3)
#4      Font.initialize (package:rive_common/rive_text.dart:463:7)
#5      RiveFile.initialize (package:rive/src/rive_file.dart:392:33)
#6      LoadDependenciesGraphWidget.setupDependenciesGraph (package:earthrangers/ui/app/app.dart:190:20)

Just got a replay from QA, the iOS devices they are using are:

• iPhone 7: iOS 15
• iPad pro 12.9" 3rd gen: iOS 18
• iPad 6th gen iOS 17.5.1

Hi,
Same issue here

Description

Simply calling RiveAnimation.asset('assets/animations/loading.riv')

No animation displayed and the following error appears in the logs.

Flutter clean and rebuild didn't help.

Works fine on Android
