Idea of Flash Auto Filled Icon
It's a black outline of a lightning bolt positioned straight up and down, with one jag in the lightning bolt. A black capital letter A in a sans-serif font is in the top right corner, with the top of the letter A level with the top point of the lightning bolt.
This is a Flash Auto Filled icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
