How to Capitalize the First Letter of a String in Dart! 💥

So, you want to make your string look all fancy by capitalizing the first letter? Well, fret no more! I've got your back. In this blog post, I'll guide you through the process of capitalizing the first letter of a string in Dart without changing the case of any of the other letters. 🌟

The Problem

Imagine you have a string like "this is a string," and you want it to be "This is a string." Sounds simple, right? But it can quickly become trickier than you anticipated. Fear not, though! We'll tackle this challenge head-on. 😉

The Solution

Here's a straightforward and elegant solution using the Dart language:

String capitalizeFirstLetter(String text) {
  return text.substring(0, 1).toUpperCase() + text.substring(1);
}

Let's break it down, shall we? 🧐

• We define a function called capitalizeFirstLetter that takes a String parameter called text.

• Inside the function, we return a new string by concatenating the following:

  • The first character of the text string, converted to uppercase using toUpperCase(). 🌈

  • The remaining characters of the text string, starting from the second character, obtained using substring(1).

Examples

Let's try out our newfound superpower with a few examples:

print(capitalizeFirstLetter("this is a string")); // Output: This is a string
print(capitalizeFirstLetter("hello, world!"));  // Output: Hello, world!
print(capitalizeFirstLetter("i lOvE dArT"));    // Output: I lOvE dArT

As you can see, the capitalizeFirstLetter function works like a charm! 🎩💫
