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

Answer

To convert a set of floats to a set of strings in Dart, you can use the map() method to transform each float value into its string representation.

✐ Examples

1 Convert a Set of Floats {1.1, 2.2, 3.3} to Strings

In this example,

First, we create a set of floats named floatSet1 with values {1.1, 2.2, 3.3}.
Next, we use the map() method to transform each float value in floatSet1 to its string representation. We do this by passing a closure to the map() method, where each element is converted to a string using the toString() method.
The map() method returns an iterable of strings. We then convert this iterable into a set of strings by using the toSet() method.
Finally, we iterate through stringSet1 and print each string value to the console to verify the conversion.

Dart Program

void main() {
  Set<double> floatSet1 = {1.1, 2.2, 3.3};
  Set<String> stringSet1 = floatSet1.map((f) => f.toString()).toSet();

  for (var str in stringSet1) {
    print(str);
  }
}

Output

1.1
2.2
3.3

2 Convert a Set of Floats {4.5, 5.6, 6.7} to Strings

In this example,

First, we create a set of floats named floatSet2 with values {4.5, 5.6, 6.7}.
Next, we use the map() method to transform each float value in floatSet2 to its string representation. We do this by passing a closure to the map() method, where each element is converted to a string using the toString() method.
The map() method returns an iterable of strings. We then convert this iterable into a set of strings by using the toSet() method.
Finally, we iterate through stringSet2 and print each string value to the console to verify the conversion.

Dart Program

void main() {
  Set<double> floatSet2 = {4.5, 5.6, 6.7};
  Set<String> stringSet2 = floatSet2.map((f) => f.toString()).toSet();

  for (var str in stringSet2) {
    print(str);
  }
}

Output

4.5
5.6
6.7
