How do ARB files let you properly organize and store your app's own translated text strings for each individual specific supported language?

ARB, meaning Application Resource Bundle, is a genuinely simple, well established JSON based file format specifically used for storing your app's own translated text strings, with each individual specific supported language genuinely stored within its own separate corresponding ARB file, such as app_en.arb for English and app_es.arb for Spanish, and Flutter's own official code generation tooling reads these particular ARB files and automatically generates the actual corresponding strongly typed Dart methods you can then genuinely call directly from within your own widget code to properly retrieve the correct translated text for whichever specific locale is currently actually genuinely active.

// app_en.arb
{
  "welcomeMessage": "Welcome to our app"
}

// app_es.arb
{
  "welcomeMessage": "Bienvenido a nuestra aplicacion"
}
