How to get data index from List Dart
202
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.)

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")
