This pull request aims for improved readability, based on issue #146600. ```dart // before Set<Color> _distinctVisibleColors() { final Set<Color> distinctVisibleColors = <Color>{}; if (top.style != BorderStyle.none) { distinctVisibleColors.add(top.color); } if (right.style != BorderStyle.none) { distinctVisibleColors.add(right.color); } if (bottom.style != BorderStyle.none) { distinctVisibleColors.add(bottom.color); } if (left.style != BorderStyle.none) { distinctVisibleColors.add(left.color); } return distinctVisibleColors; } // after Set<Color> _distinctVisibleColors() { return <Color>{ if (top.style != BorderStyle.none) top.color, if (right.style != BorderStyle.none) right.color, if (bottom.style != BorderStyle.none) bottom.color, if (left.style != BorderStyle.none) left.color, }; } ``` Most of the repo should be covered in this PR (aside from `flutter_tools/`, since there was a lot going on in there).
