How to get data index from List Dart

Question

I have the list data like this

void main() {
  var animals = [
    {
      "0": ["cow", "chicken", "Fish"]
    },
    {
      "1": ["lamb", "Camel"]
    },
    {
      "2": ["Goat", "Cat"]
    }
  ];
  print(animals.length);
  for (var a in animals) {
for (final x in a.entries){
print (x.value)}
}

}

but I want to get data to become like this:

1. cow 
2. chicken
3. fish
1. lamb
2. camel
1. goat
2. cat

So, what can I do to get the output? Thank you I have tried to use join, but it is just for making a new line. not get the index.

Using x.value.join("\n")

try using .indexWhere and use a filter that includes all of your data. (https://www.kindacode.com/snippet/dart-flutter-get-the-index-of-a-specific-element-in-a-list/#:~:text=In%20Dart%2C%20the%20List%20class,that%20satisfies%20the%20given%20conditions.)
