      Remove 'must not be null' comments from painting and rendering libraries. (#134993) · fe9a2c54
      Greg Spencer authored
      ## Description
      
      This removes all of the comments that are of the form "so-and-so (must not be null|can ?not be null|must be non-null)" from the cases where those values are defines as non-nullable values.
      
      This PR removes them from the painting and rendering libraries.
      
      This was done by hand, since it really didn't lend itself to scripting, so it needs to be more than just spot-checked, I think. I was careful to leave any comment that referred to parameters that were nullable, but I may have missed some.
      
      In addition to being no longer relevant after null safety has been made the default, these comments were largely fragile, in that it was easy for them to get out of date, and not be accurate anymore anyhow.
      
      This did create a number of constructor comments which basically say "Creates a [Foo].", but I don't really know how to avoid that in a large scale change, since there's not much you can really say in a lot of cases.  I think we might consider some leniency for constructors to the "Comment must be meaningful" style guidance (which we de facto have already, since there are a bunch of these).

      Replaces `textScaleFactor` with `TextScaler` (#128522) · b2e22d35
      LongCatIsLooong authored
      Deprecate `textScaleFactor` in favor of `textScaler`, in preparation for Android 14 [Non-linear font scaling to 200%](https://developer.android.com/about/versions/14/features#non-linear-font-scaling). The `TextScaler` class can be moved to `dart:ui` in the future, if we decide to use the Android platform API or AndroidX to get the scaling curve instead of hard coding the curve in the framework.
      
      I haven't put the Flutter version in the deprecation message so the analyzer checks are failing. Will do so after I finish the migration guide.
      
      **Why `TextScaler.textScaleFactor`**
      The author of a `TextScaler` subclass should provide a fallback `textScaleFactor`. By making `TextScaler` also contain the `textScaleFactor` information it also makes it easier to migrate: if a widget overrides `MediaQueryData.textScaler` in the tree, for unmigrated widgets in the subtree it would also have to override `MediaQueryData.textScaleFactor`, and that makes it difficult to remove `MediaQueryData.textScaleFactor` in the future.
      
      ## A full list of affected APIs in this PR
      
      Deprecated: The method/getter/setter/argument is annotated with a `@Deprecated()` annotation in this PR, and the caller should replace it with `textScaler` instead. Unless otherwise specified there will be a Flutter fix available to help with migration but it's still recommended to migrate case-by-case.
      **Replaced**:  The method this `textScaleFactor` argument belongs to is rarely called directly by user code and is not overridden by any of the registered custom tests, so the argument is directly replaced by `TextScaler`.
      **To Be Deprecated**:  The method/getter/setter/argument can't be deprecated in this PR because a registered customer test depends on it and a Flutter fix isn't available (or the test was run without applying flutter fixes first). This method/getter/setter/argument will be deprecated in a followup PR once the registered test is migrated.

      A lot of material widgets (`Slider`, `RangeSlider`, `TimePicker`, and different types of buttons) also change their layout based on `textScaleFactor`. These need to be handled in a case-by-case fashion and will be migrated in follow-up PRs.

      Move shared inline widget logic to `RenderInlineWidgetContainerDefaults` (#127308) · b5df180a
      LongCatIsLooong authored
      - Added `InlineWidgetContainerDefaults` for deduping inline widget code
      - Added a helper function `WidgetSpan.extractFromInlineSpan` for extracting `WidgetSpan`s and automatically applying text scaling (at widget level)
      - Removed `TextPainter.inlinePlaceholderScales`. I'm going to deprecate the `scale` argument in `TextPainter.addPlaceholder` next, as scaling is now done at the widget level.
      - Added runtime check and comments to make sure nobody is extending `PlaceholderSpan` directly (unfortunately we can't remove `PlaceholderSpan`  without moving RenderEditable and RenderParagraph to the widgets library).

      Add `InlineSpan.visitDirectChildren` (#125656) · f704c689
      LongCatIsLooong authored
      I'd like to find out the `fontSize` of a `PlaceholderSpan`, and currently there doesn't seem to be a way to do `TextStyle` cascading in the framework:
      
       `InlineSpan.visitChildren` traverses the entire `InlineSpan` tree using a preorder traversal, and nodes that don't have "content" will be skipped (https://master-api.flutter.dev/flutter/painting/InlineSpan/visitChildren.html): 
      
      > Walks this [InlineSpan](https://master-api.flutter.dev/flutter/painting/InlineSpan-class.html) and any descendants in pre-order and calls visitor for each span that has content.
      
      which makes it impossible to do `TextStyle` cascading in the framework: 
      - `InlineSpan`s with a non-null `TextStyle` but has no content will be skipped
      - `visitChildren` doesn't directly expose the hierarchy, it only gives information about the flattened tree.
      
      This doesn't look like a breaking change, most internal customers are extending `WidgetSpan` which has a concrete implementation of the new method.
      
      Alternatively I could create a fake `ui.ParagraphBuilder` and record the `ui.TextStyle` at the top of the stack when `addPlaceholder` is called. But `ui.TextStyle` properties are not exposed to the framework.

      Some were already marked "The Flutter Authors", not clear why. Their
