Reading image by name

[BassirouRabo]

Is is possible to read image by name as a string at runtime?

Hello. Everything is same as in native development. In Android this possible only via reflection. For iOS / JVM / JS you can write helper to get it by string.

Could you send sample for android and ios?

For iOS you need to know name of bundle. You can view it by path yourModule/build/generated/libres/apple/libres-bundles. For example my bundle is named LibresShared

// common
expect fun MainResImages.getByName(name: String, extension: String): Image

// android
actual fun MainResImages.getByName(name: String, extension: String): Image =
   this::class.java.getDeclaredMethod("get${name.replaceFirstChar { it.uppercase() }}").invoke(this) as Image

// ios
actual fun MainResImages.getByName(name: String, extension: String): Image =
    NSBundle.bundleWithName("LibresShared").image(name, extension)

// usage
MainResImages.images.getByName("example", "png")

But you need to remember that in release build of your Android app if you enable obfuscation, names of variables and methods change and such call will cause a runtime crash.

@Skeptick thanks for you support. It looks like NSBundle.bundleWithName("LibresShared").image(name, extension) returns UIImage instead of Image. I am having issue at this point

@Skeptick any update regarding this?
