How Rorate a Flutter Icon

To rotate Icons.arrow_back by 45° in Flutter, wrap it with Transform.rotate.

Example: rotate 45 degrees

Transform.rotate(
  angle: 45 * 3.1415926535 / 180, // 45 degrees in radians
  child: Icon(Icons.arrow_back),
)

Cleaner version

import 'dart:math';

Transform.rotate(
  angle: pi / 4,
  child: Icon(Icons.arrow_back),
)

Direction reference

• pi / 4 → 45° clockwise
• -pi / 4 → 45° counter-clockwise

So if you want it to point up-left, rotate counter-clockwise:

Transform.rotate(
  angle: -pi / 4,
  child: Icon(Icons.arrow_back),
)
