How to Convert a Set of Strings to a Set of Floats in Dart - Step by Step Examples

How to Convert a Set of Strings to a Set of Floats in Dart ?

Answer

To convert a set of strings to a set of floats in Dart, you can use the map method to transform each string into a float and then create a new set from the resulting iterable.

✐ Examples

1 Convert Set of Strings to Set of Floats Example 1

In this example,

First, we create a set named stringSet1 using the {} syntax, which contains the string values '1.1', '2.2', and '3.3'.
Next, we use the map method on stringSet1 to transform each string into a float using the double.parse function.
We convert the resulting iterable to a set using the toSet method, resulting in a set of floats named floatSet1.
Finally, we print the set of floats using print.

Dart Program

void main() {
  var stringSet1 = {'1.1', '2.2', '3.3'};
  var floatSet1 = stringSet1.map((str) => double.parse(str)).toSet();
  print(floatSet1);
}

Output

{1.1, 2.2, 3.3}

2 Convert Set of Strings to Set of Floats Example 2

In this example,

We create a set named stringSet2 using the {} syntax, which contains the string values '4.4', 'hello', '5.5', '6.6', and 'world'.
We use the map method on stringSet2 to transform each string into a float using the double.parse function.
We convert the resulting iterable to a set using the toSet method, resulting in a set of floats named floatSet2.
Finally, we print the set of floats using print.

Dart Program

void main() {
  var stringSet2 = {'4.4', 'hello', '5.5', '6.6', 'world'};
  var floatSet2 = stringSet2.map((str) => double.parse(str)).toSet();
  print(floatSet2);
}

Output

{4.4, 5.5, 6.6}
