Changes

High Priority

• ✅ Axis styling should use Roboto Condensed.
• ✅ Axis should have an easier to understand interval. For example, each 5000 instead of each 3100.
• ✅ X Axis should not have tilted text. Instead, reduce the interval in which text appears, like once per month.
• ❓ Vertical bars should shrink in the "Tudo" view, keeping 1dp of distance.
• ❓ On selection, the selected bar should be dark green
• 🚫 The selection bubble should have the selected day
• ❓ The selection bubble should not have decimals
• ✅ The data on the "Proporção UCI" doesn't seem correct.
• 🚫 Some graphs were designed to be horizontal. I understand it may be difficult to make entirely new graphs for this, but the readability is impacted if they're vertical.

Medium priority

• ❓ Distances appear to be wrong. Please confirm with the Zeplin project.
• ❓ Missing graph for Geographic zones?
• ❓ Vertical lines should not have the same style as the horizontal ones.

Small priority

-❓ Style details that don't have a major impact on usability

Overall looks good to me, I've suggested some optional changes. Apply it if you have the time, otherwise it's ok to merge.

Since this is in a Column we can avoid ternary that will add an "invisible" widget to the tree. We can make it if( checkHasAgeGroupData(currentStatistics.confirmedRecentByAgeGroup)) Padding(...) instead.

I'd rather have this 0 as default values on the constructor.

Make it const.
