Best way to get all strings and save it in array?

Hi.

1. What would be the best way to get all the strings and save them in array? So I could use it in ListView?

2. Is it possible to "categorize" strings inside string_en.json file? Or if not, what would be the best logic to save into array just strings that starts with card_category1_?

{
  "card_category1_test": "test",
  "card_category1_abc": "abc",
  "card_category2_test": "Another test",
  "card_category2_abc": "Another abc"
}

For question 1, currently, need to write a helper function which contain many switch cases to map with a specific function

Maybe enhance for the future with following solutions.

S.of(context).localized(name, args) eg.

S.of(context).localized('card_category1.test')

For question 2, Thinking of using json structure

{
  "card_category1": {
	"test": "test"
	"abc": "abc"
  },
  "card_category2": {
	"test": "Another test"
	"abc": "Another abc"
  }
}

But, the generated function name will be tricky. Thats why we need a generalize function like S.of(context).localized(name, args)
