Flutter uses hexadecimal ARGB values for colors, which are formatted as const Color(0xAARRGGBB). That first pair of letters, the AA, represent the alpha channel. You must convert your decimal opacity values to a hexadecimal value. Here are the steps:

Alpha Hex Value Process

Take your opacity as a decimal value and multiply it by 255. So, if you have a block that is 50% opaque the decimal value would be .5. For example: .5 x 255 = 127.5
The fraction won't convert to hexadecimal, so you must round your number up or down to the nearest whole number. For example: 127.5 rounds up to 128; 55.25 rounds down to 55.
Enter your decimal value in a decimal-to-hexadecimal converter, like http://www.binaryhexconverter.com/decimal-to-hex-converter, and convert your values.

FYI, 8 простых шагов по настройке оповещений из гитхаба в слак:

добавляете email интеграцию ( https://DOMAIN.slack.com/apps/A0F81496D-email )
в post to channel выбираете private to you
вписываете описание, например Notifications from github
указываете имя бота, например Github
добавляете иконку, например https://s3-us-west-2.amazonaws.com/slack-files2/avatars/2016-08-15/69493433745_7e0ca8bcd7eae89b6b99_48.png
После добавления интеграции – получаете персональный email от слака.
Идёте на гитхаб, в раздел Emails ( https://github.com/settings/emails ) и добавляете туда полученный адрес.
Переходите в раздел Notifications ( https://github.com/settings/notifications ), выбираете у нужных событий галочки Email, в списке выбираете новый email. PROFIT!
