How to remove empty lists from a list in Dart?

Issue

I have an issue in my Dart Programme. Here is a list of emojis:

[[🐃, 💧, 💦], [], [🌵, 🎄, 🌲], [], [], []] //List

Inside the list there are multiple lists (as you can see). I want to remove empty lists []. Also I want to Join [🐃, 💧, 💦, 🌵, 🎄, 🌲] into a single list.

Solution

Full Solution:

var data = [['🐃', '💧', '💦'], [], ['🌵', '🎄', '🌲'], [], [], []];

void main() {
  var newData = data.expand((x) => x).toList();
  print(newData);
}

Here, newData is your final answer as: [🐃, 💧, 💦, 🌵, 🎄, 🌲].
