How to get Substring before Specific Character in Dart ?

Answer

To get the substring before a specific character in Dart, you can use the `substring` method along with the `indexOf` method to find the position of the character.

✐ Examples

1 Substring Before '/' in "https://example.com/page"

In this example,

We create a variable named url with a value of "https://example.com/page".
We use the indexOf method to find the position of '/'.
We use the substring method with the starting index of 0 and the index of '/' to get the substring before the specified character.
Finally, we display the substring.

Dart Program

void main() {
  String url = 'https://example.com/page';
  int index = url.indexOf('/');
  String substring = url.substring(0, index);
  print('Substring before '/': $substring');
}

Output

Substring before '/': https:

2 Substring Before ',' in "Hello,World"

In this example,

We create a variable named str with a value of "Hello,World".
We use the indexOf method to find the position of ','.
We use the substring method with the starting index of 0 and the index of ',' to get the substring before the specified character.
Finally, we display the substring.

Dart Program

void main() {
  String str = 'Hello,World';
  int index = str.indexOf(',');
  String substring = str.substring(0, index);
  print('Substring before ',': $substring');
}

Output

Substring before ',': Hello
