问题
As you can see in the picture below, the texts have the same amount of characters, but since the number "1" is slimmer than the "5" and "2", both texts get a different width.
How can I adjust that in Flutter?
回答1:
Use a monospaced font, also called a fixed-pitch, fixed-width, or non-proportional font, is a font whose letters and characters each occupy the same amount of horizontal space.
Wikipedia explains it well. https://en.wikipedia.org/wiki/Monospaced_font

Hiepav suggestion, seems a good approach because you are not doing nothing wrong but each character in the font have different widths so it will have to adjust to give enough room.
However, as a workaround you can actually wrap your texts in a fixed width sized box that gives enough space for both widgets regarding its character widths variations , such as SizedBox, ConstrainedBox or even Container with width constraints and center align child. This way, with that font, you should at least have the : vertically aligned.
