color property Null safety

Color? color
@JsonKey(includeIfNull: false, fromJson: _$ColorFromJson, toJson: _$ColorToJson), read / write

The color of the custom background image. The format is a hexadecimal integer defined by RGB, without the # sign, such as 0xFFB6C1 for light pink. The default value is 0xFFFFFF, which signifies white. The value range is 0x000000,0xffffff. If the value is invalid, the SDK replaces the original background image with a white background image.

Note

This parameter takes effect only when the type of the custom background image is color.

Implementation

    includeIfNull: false, fromJson: _$ColorFromJson, toJson: _$ColorToJson)
Color? color;
