use_full_hex_values_for_flutter_colors

Prefer an 8-digit hexadecimal integer (for example, 0xFFFFFFFF) to instantiate a Color.

This rule is available as of Dart 2.2.

Rule sets: flutter

This rule has a quick fix available.

PREFER an 8-digit hexadecimal integer (for example, 0xFFFFFFFF) to instantiate a Color. Colors have four 8-bit channels, which adds up to 32 bits, so Colors are described using a 32-bit integer.

BAD:

Color(1);
Color(0x000001);

GOOD:

Color(0x00000001);

To enable the use_full_hex_values_for_flutter_colors rule, add use_full_hex_values_for_flutter_colors under linter > rules in your analysis_options.yaml file:
