✐ Examples

1 Writing character code 65 to the buffer

In this example,

  1. We create a `StringBuffer` named `buffer`.
  2. We use the `writeCharCode()` method to add the character represented by the code 65 ('A') 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.writeCharCode(65);
  print(buffer.toString());
}

Output

A

2 Writing character code 97 to the buffer

In this example,

  1. We create a `StringBuffer` named `buffer`.
  2. We use the `writeCharCode()` method to add the character represented by the code 97 ('a') 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.writeCharCode(97);
  print(buffer.toString());
}

Output

a

3 Writing character code 33 to the buffer

In this example,

  1. We create a `StringBuffer` named `buffer`.
  2. We use the `writeCharCode()` method to add the character represented by the code 33 ('!') 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.writeCharCode(33);
  print(buffer.toString());
}

Output

!
