How to call print() with colorful text to android studio console in flutter

I created the screenshots and code below in VS Code, but supposedly it also works in Android Studio now too:

enter image description here

void main() {
  print('This is a normal message.');
  printWarning('This is a warning.');
  printError('This is an error.');

void printWarning(String text) {

void printError(String text) {

ANSI escape code explanation

The ANSI escape code string is pretty confusing if you’re not familiar with the format.

enter image description here

Here is the string to turn Hello red:


And here it is again with spaces added for clarity between the parts:

\x1B  [31m  Hello  \x1B  [0m


  • \x1B: ANSI escape sequence starting marker
  • [31m: Escape sequence for red
  • [0m: Escape sequence for reset (stop making the text red)

Here are the other colors:

Black:   \x1B[30m
Red:     \x1B[31m
Green:   \x1B[32m
Yellow:  \x1B[33m
Blue:    \x1B[34m
Magenta: \x1B[35m
Cyan:    \x1B[36m
White:   \x1B[37m
Reset:   \x1B[0m
