How to convert String to Float in Dart - Step by Step Examples

How to convert String to Float in Dart ?

To convert a string to a float in Dart, you can use the 'double.parse()' function.

In this example,

We create a string variable str1 with a value of "3.14".
We use the double.parse() function to convert the string to a float and store the result in a variable float1.
Finally, we print the float value float1.

// Convert "3.14" String to Float
void main() {
  String str1 = "3.14";
  double float1 = double.parse(str1);
  print("Float value is: $float1");
}

Float value is: 3.14

In this example,

We create a string variable str2 with a value of "10.5".
We use the double.parse() function to convert the string to a float and store the result in a variable float2.
Finally, we print the float value float2.

// Convert "10.5" String to Float
void main() {
  String str2 = "10.5";
  double float2 = double.parse(str2);
  print("Float value is: $float2");
}

Float value is: 10.5
