Consider documenting Stripping iOS symbols for SPM ipa builds with bundled assets

Description

Currently, at least using SPM, we experience an error on IPA builds (debugging works fine).

An error is thrown:

RiveFileLoaderException: Failed to load
Rive file from asset: packages/my_package/assets/my_rive_file.riv.
Error: Invalid arguments): Failed to lookup symbol 'loadRiveFile': dlsym(RTLD_DEFAULT, loadRiveFile):
symbol not found
#0 FileLoader.file (package:rive/src/ file_loader.dart:66)
<asynchronous suspension>
#1
_RiveWidgetBuilderState._setuplmpl
(package:rive/src/widgets/ rive_builder.dart:130)
<asynchronous suspension>
#2 _RiveWidgetBuilderState._setup (package:rive/src/widgets/ rive_builder.dart:108)
<asynchronous suspension>

Steps To Reproduce

Steps to reproduce the behavior:

1. Use a rive flutter project with bundled assets
2. Use SPM via flutter config --enable-swift-package-manager
3. In Xcode, go to Target Runner > Build Settings > Strip Style.

• Just ensure: The default should be All Symbols

5. Deploy an IPA, (I was only able to reproduce it via a TestFlight build or in Prod.

Source .riv/.rev file

Every bundled asset should lead to that behavior.

Expected behavior

Document that stripping iOS symbols should be targeted to only non-global symbols, see https://docs.flutter.dev/platform-integration/ios/c-interop#stripping-ios-symbols

 When creating a release archive (IPA), the symbols are stripped by Xcode.

    In Xcode, go to Target Runner > Build Settings > Strip Style.
    Change from All Symbols to Non-Global Symbols.

Locate the project’s documentation entry point for iOS and SPM builds, then review the linked Flutter iOS C interop guidance. Document the Xcode Target Runner > Build Settings > Strip Style change from All Symbols to Non-Global Symbols, including that it applies when creating a release IPA with bundled assets.
