Word Split

WordSplit.js

function WordSplit(strArr) {
  const word = strArr[0];
  const substrings = generateSubstrings(word);
  const words = substrings.filter(substring => strArr[1].includes(substring));
  const pairs = generatePairs(words);
  const pair = pairs.find(pair => pair.join('') === word);
  return pair ? pair.join(',') : 'no pair';
}

function generateSubstrings(str) {
  const substrings = [];
  for (let i = 0; i < str.length; i++) {
    for (let j = i + 1; j < str.length + 1; j++) {
      substrings.push(str.slice(i, j));
    }
  }
  return substrings;
}

function generatePairs(arr) {
  const pairs = [];
  for (let i = 0; i < arr.length; i++) {
    for (let j = i; j < arr.length - 1; j++) {
      pairs.push([arr[i], arr[j + 1]]);
    }
  }
  return pairs;
}

console.log(WordSplit([ 'baseball', 'a,all,b,ball,bas,base,cat,code,d,e,quit,z' ])); // base,ball
console.log(WordSplit([ 'abcgefd', 'a,ab,abc,abcg,b,c,dog,e,efd,zzzz' ])); // abcg,efd

can you convert this code to dart code please?

Sure I'll look into doing that at some point!
