TypeError: Cannot read properties of undefined (reading 'loadFontFromFile')

[nolife08021]

hi, I facing this error when trying to use loadFontFromFile function

TypeError: Cannot read properties of undefined (reading 'loadFontFromFile')

[nolife08021]

After i add pod 'ReactNativeDynamicFont', :path => "../node_modules/react-native-dynamic-font/ios", the error gone, but new error comes out.

Thread 1: EXC_BAD_ACCESS (code=1, address=0x489d2cdd01d0)

Solution is replace this line from ReactNativeDynamicFont.m:
NSString *path = [options valueForKey:@"path"];

to:

NSString *path = [options valueForKey:@"filePath"];

And use patch-package to make it works!

[vladlenskiy]

So, this is my react-native-dynamic-font+1.0.8.patch file, after that this library work for me:

Use Patch Package library to make it works!
