How to concatenate a class with a variable to get a static variable from this class? - flutter

Question

I am making a pokemon app and I have a question that I already had in other projects and I would like to know if anyone can help me with a solution.
I receive a variable called pokemonName from other screen, I want to pass the variable and concatenate with the class "Strings", it will be like Strings.+pokemonName.toLowerCase(), converting to lowercase to get the map from the class Strings, but I don't know how to achieve this to remove the switch and don't need to use a lot of cases for each pokemon.
class PokemonDetailScreen extends StatelessWidget {
final String pokemonName;
final String image;
Map<String, dynamic> pokemonMap = {};
PokemonDetailScreen(this.pokemonName, this.image, this.index){
getPokemonMap();
}
#override
Widget build(BuildContext context) {
return Container();
}
void getPokemonMap(){
switch(pokemonName){
case "Bulbasaur":
pokemonMap = Strings.bulbasaur;
break;
case "Charmander":
pokemonMap = Strings.charmander;
break;
}
}
}
**Class in another dart file:**
class Strings {
static Map bulbasaur = {};
}
What I needed is something like this:
void getPokemonMap(){
pokemonMap = Strings.$pokemonMap.toLowerCase();
}

What you could do is have a static map indexed by the name of your Pokemons and whose values are maps.
class Strings {
static Map<String, dynamic> map = {
'Bulbasor': {},
'Charmander': {},
// ...
};
}
And you’ll use it like this: pokemonMap = Strings.map[pokemonName].

~You can use JSON file to do all this things instead use a class.~
I recommend not use a static class to do that thing, instead you can just make a normal class and instantiate on another file, so when the class that you call your another class will be dispose when the parent was.
class PokemonStrings {
Map bulbasaur = {your map here};
}
To call that in another file you need just do
PokemonString _pokemonString = PokemonString();
And call whatever you need in the class that you instantiate
var bulbasaurMap = _pokemonString.bulbasaur;
But even so you need walk with static class. Just call the name of class followed by dot to access all the static attributes
var bulbasaurMap = PokemonString.bulbasaur;
