Fix linux compilation errors

[Snowcrash5]

It seems that sometime the option to turn warnings into errors was turned on
Some functions are only used by asserts so in release they become unused functions.

This fixes compilation on Ubuntu 24.04

@Snowcrash5 Hey. What compiler and version?

Both of these work (release) with GCC 13 and Clang 18 (scarthgap):
https://github.com/meta-flutter/meta-flutter/blob/scarthgap/recipes-graphics/rive/rive-text_0.4.11.bb
https://github.com/meta-flutter/meta-flutter/blob/scarthgap/dynamic-layers/clang-layer/recipes-graphics/rive/rive-text_0.4.11.bbappend

Also there is only a main branch.

gcc (Ubuntu 13.2.0-23ubuntu4) 13.2.0
Ubuntu clang version 18.1.3 (1ubuntu1)

It happens when I build my Flutter app with the normal rive package in it.

Looks like there's already an issue:
rive-app/rive-flutter#390

[jwinarske]

I see. This repo was specifically made for building librive_text.so for Yocto Linux; which has no compilation issues.

Oh I see. Seems like theres no rive common repo, all comes via the pub package... Well lets hope they see this on that issue :)
