Filter strings containing a word in Flutter

Solution 1:

Might not be the most performant, but unless you're doing this on millions of items, there shouldn't be any problem:

final l = [
  'That is a list of some animals',
  'That is a list of something like animals',
  'That is a list of handsome animals',
];

l.retainWhere((str) => str.split(' ').any((word) => word.startsWith('some')));

Solution 2:

The question is already been answered in the simplest form of code. But I am doing it in a layman's way.

final list = [
  'That is a list of some animals',
  'That is a list of something like animals',
  'That is a list of handsome animals',
];
  
for(var i = 0 ; i < list.length ; i++){
  var sentence = list[i].split(' ');
  bool found = false;

  for(var j = 0 ; j < sentence.length ; j++){    
    if (sentence[j].startsWith('some')){
      found = true;
    }
  }

  if(!found){
    list.removeAt(i);
    found = false;
  }
}

1. Stored three sentences in the list.
2. Used a loop to get each sentence.
3. Split the sentence on the basis of space, to get each word.
4. Used an array to check each word of the sentence, whether it is starting from some
5. If any word of the sentence is starting from some, then I removed that sentence from the list
