Convert Variable From Float To String In Dart

In the realm of functionality and efficiency, Dart language continues to be a standout among the prominent languages for developers. One frequent task developers undertake is converting variables from float to string, and Dart provides mechanisms to achieve this conversion quite effortlessly.

Code snippet for converting Float to String

Here is a simple dart code that can be used to convert float to string:

void main() {
  double doubleVar = 12.34; //float value
  String stringVar = doubleVar.toString();
  print(stringVar);
}

Code Explanation for converting Float to String

In the given sample code, we are trying to convert a double (float in Dart is denoted as double) to a string. Let’s go over this step by step.

Step 1: First, we define a double variable, doubleVar, and assign it a value of 12.34.

double doubleVar = 12.34; //float value

Step 2: The next step is to convert this double into a string. Dart provides us with an inbuilt function toString() for just this. This function, just as the name suggests, converts an object to its string representation. Here, we are calling this method on the double variable doubleVar to get its string representation. The result is assigned to a new variable stringVar of type String.

String stringVar = doubleVar.toString();

Hence stringVar now contains the string value of the float number.

Step 3: We will then print this string to the console to make sure our conversion has happened correctly.

print(stringVar);

After running this code, we should see 12.34 printed on the console as a result.

While performing such operations, it is necessary to handle values properly, considering the precision and format of the output string. Dart makes these conversions fairly straightforward, allowing developers to focus on more intricate aspects of their projects.
