✐ Examples

1 Writing an integer to the buffer

In this example,

  1. We create a `StringBuffer` named `buffer`.
  2. We use the `write()` method to add the integer value 42 to the buffer.
  3. We convert the buffer to a string using `toString()` and print it to standard output.

Dart Program

void main() {
  StringBuffer buffer = StringBuffer();
  buffer.write(42);
  print(buffer.toString());
}

Output

42

2 Writing a string to the buffer

In this example,

  1. We create a `StringBuffer` named `buffer`.
  2. We use the `write()` method to add the string 'Hello' to the buffer.
  3. We convert the buffer to a string using `toString()` and print it to standard output.

Dart Program

void main() {
  StringBuffer buffer = StringBuffer();
  buffer.write('Hello');
  print(buffer.toString());
}

Output

Hello

3 Writing a list to the buffer

In this example,

  1. We create a `StringBuffer` named `buffer`.
  2. We use the `write()` method to add the list ['This', ' is', ' a', ' list'] to the buffer.
  3. We convert the buffer to a string using `toString()` and print it to standard output.

Dart Program

void main() {
  StringBuffer buffer = StringBuffer();
  buffer.write(['This', ' is', ' a', ' list']);
  print(buffer.toString());
}

Output
