Remove words except last one in String-CodePudding

I have a String with different value every time:

String words = "My name is Rob Joe";

I want to get only last word

Joe

but every time I don't know how many words the string consists of

CodePudding user response：

In Flutter(Dart), you can get the last word of a string by splitting the string into an array of substrings using the split method and then accessing the last element of the resulting array. Here's an example:

   String words = "My name is Rob Joe";
   List<String> wordsArray = myString.split(" ");
   String lastWord = wordsArray[wordsArray.length - 1];
   print(lastWord); // "Joe"

CodePudding user response：

String words = "My name is Rob Joe";
var array = words.split(" "); // <-- [My, name, is, Rob, Joe]
print(array.last); // output 'Joe'

CodePudding user response：

Instead of splitting, you can also use substring and lastIndexOf:

final words = "My name is Rob Joe";
final lastWord = words.substring(words.lastIndexOf(" ")   1);
print(lastWord);
