Makes badge sizes it self according to child. Previously, the bubble fixed its height to 16pixel. It clip the content if it is taller than 16 pixel. This causes an issue where user can increase font size in the android setting and mess up the ui Now, the bubble can have various height from 16 pixel to the height of the child, it also extend the width to be the same as height if the child's width < height. There is minor changes to floating location in the test. I can't really fix them unless I change some of the public API like `Badge(offset)` or `BadgeThemeData.largeSize`. They are used differently in the new logic since now the badge can be larger than the Badge.child. I figure they are kind of minor so i think it should be ok Before the fix  After the fix  fixes https://github.com/flutter/flutter/issues/146777 ## Pre-launch Checklist - [ ] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [ ] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [ ] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [ ] I signed the [CLA]. - [ ] I listed at least one issue that this PR fixes in the description above. - [ ] I updated/added relevant documentation (doc comments with `///`). - [ ] I added new tests to check the change I am making, or this PR is [test-exempt]. - [ ] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [ ] All existing and new tests are passing.
