Should fix#22226.
Code introduced in #20890 caused a regression that broke color flooding animations in a BottomNavigationBar that has BottomNavigationBarType.shifting.
The original issue (#19653) dealt with background color changes not occurring until another tab was selected. The result is that the background color instantly changes whenever the state changes and when the widget changes, instead of allowing a new widget to animate the background color change.
This rewrites the sample code analysis script to be a little less of a hack (but still not pretty), and to handle snippets as well.
It also changes the semantics of how sample code is handled: the namespace for the sample code is now limited to the file that it appears in, so some additional "Examples can assume:" blocks were added. The upside of this is that there will be far fewer name collisions.
I fixed the output too: no longer will you get 4000 lines of numbered output with the error at the top and have to grep for the actual problem. It gives the filename and line number of the original location of the code (in the comment in the tree), and prints out the source code on the line that caused the problem along with the error.
For snippets, it prints out the location of the start of the snippet and the source code line that causes the problem. It can't print out the original line, because snippets get formatted when they are written, so the line might not be in the same place.
This stops reading from pipe-to-file log after the build is completed. Attempting to read from pipe-to-file keeps open blocked because nobody is going to write into that pipe.
It's not usual for this not to be set, but it affected at least one user (#23909) and there are a non-zero number of people online saying it's not set. It's better that we don't crash.
Fixes#23909.
`RenderEditable.paint` assumes that if the length of the text fits within the
visible region, then the text will be rendered at the start of the region and be
completely visible. This is not always true, since the text may still be
rendered at an offset if an animation is ongoing when the text begins to fit.
This fixes#22288 and #14121
