Split A String In Dart

In programming, string manipulation is a common task and the need to split a string can often arise. This article will provide a simple tutorial on how to split a string in Dart programming language.

Code snippet for Splitting a String in Dart

Below is a simple Dart code snippet that demonstrates how to split a string.

void main() {
  String str = "Hello World!";
  var strArray = str.split(" ");
  
  print(strArray);
}

In this code, we are splitting the string ‘Hello World!’ wherever a space character ’ ’ is found.

Code Explanation for Splitting a String in Dart

Let’s break down the above code snippet and explain it step by step.

1. void main() {} - This is the main method, which marks the entry point of our Dart program.

2. String str = "Hello World!"; - Here, we declare a string named str and initialize it with the value "Hello World!".

3. var strArray = str.split(" "); - This is where the string splitting happens. The split() method is a built-in method in Dart that splits a string around matches of the given delimiter. In this case, it splits the string every time it encounters a space character ’ ‘. The result is a list of substrings.

4. print(strArray); - This line prints the resulting list to the console.

When you run this code, it will print: [Hello, World!]. This means the string has been successfully split into two separate strings - "Hello" and "World!", based on the space delimiter.

That’s it! That’s how you can effortlessly split a string into a list of substrings in Dart. You can replace the space character with whatever character you wish to split the string on. Try to experiment with different characters and multiple words.
