* JSON.decode produces Map<String, dynamic> and List<dynamic>
objects. If a more tight type is required then object needs to
be converted explicitly (see dart-lang/sdk#31876);
* Completer<dynamic> produces Future<dynamic>. In Dart 2 it is
runtime error to assign Future<dynamic> to variable of type Future<T>;
Apple encodes syslog entries using a 7-bit encoding where input UTF-8 bytes
are encoded as follows:
1. 0x00 to 0x19: non-printing range. Some ignored, some encoded as <...>.
2. 0x20 to 0x7f: as-is, with the exception of 0x5c (backslash).
3. 0x5c (backslash): octal representation \134.
4. 0x80 to 0x9f: \M^x (using control-character notation for range 0x00 to 0x40).
5. 0xa0: octal representation \240.
6. 0xa1 to 0xf7: \M-x (where x is the input byte stripped of its high-order bit).
7. 0xf8 to 0xff: unused in 4-byte UTF-8.
As there doesn't appear to be a system tool to decode these strings, we
implement here in Dart. If we're unable to decode a string (e.g.
decoding results in an invalid UTF-8 string), we fall back to emitting
the log line as-is.
* Revive "Push physical layers with paths instead of rects in RenderPhysicalModel. (#13942)"
That commit was reverted due to a performance problem which has now been
fixed.
* Roll engine 05fe72d068e19c7886e8d27f9b004201d5ad1300
* Reland 9534082fc097dadf075c1eda7938af48df59ce3e with fix for incremental compilation.
When in incremental mode, awaiting exitCode won't work because compiler is not expected to exit after compilation.
Instead listen for stdout stream closing and report error if outputFilename has not been received.
* Fix lints
In the packaged ZIP files for Flutter we bundle mingit on Windows to make setup for our users easier (they don't have to download and install git anymore). This change makes Flutter use the bundled mingit if it is available and if git is not installed on the system.
This change will still require that users add `flutter\bin` to their path or they'll have to execute `flutter\bin\flutter.bat` directly. A follow-up PR will add a pre-configured Flutter Console that people can start with a double-click to minimize setup even further.
Also in this PR:
* If 7Zip is not available to unpack the Dart SDK try 7Zip's standalone version.
This provides a way to draw colors, images, and general decorations on Material widgets, without interfering with InkWells that are further descendants of the widget.
This thus provides a cleaner way to solve the issue of FlatButtons and InkWells not working when placed over Image widgets than the old hack of introducing a transparency Material.
Fixes#3782.
Also, some fixes to documentation, and remove a redundant property on the Image widget.
* Revert "Reverting package changes until I can figure out how to fix Windows. (#14007)"
This reverts commit 6fda8ee821dd2e63e7949e57b10efde84bb0a3cc.
* Make prepare_package run on Windows
* libtxt now calculates selection rectangles reflecting the heights of
differently styled text spans within a line (matching Blink)
* libtxt does not round the coordinates of selection rectangles (unlike Blink)
Fixes https://github.com/flutter/flutter/issues/12553
The root cause of https://github.com/flutter/flutter/issues/12553 was that when the refresh indicator went away, which happened after the avatars had started their image loads but before the avatars had loaded, the DecoratedBoxes, along with the rest of the list, got GlobalKey-reparented, which caused the RenderDecoratedBox objects to unregister from the DecorationImagePainters, but they never re-registered since the whole subtree was in a RepaintBoundary and was therefore not explicitly repainted when the tree got reattached.
This fixes the bug by explicitly requiring any RenderDecoratedBox to repaint when it's reattached. This is probably a little more aggressive than required; we could probably expose a flag on Decoration that says whether or not the onChanged handler will ever be invoked, and only call markNeedsPaint if that's true, but we'll do that if it turns out that there's a performance issue here.
(This patch also introduces a bunch of improved debugging information that I used to track down the bug.)
* Revert "Fixed output validation. (#14005)"
This reverts commit d84398db72807f8910833d5fe44a097be152c74a.
* Revert "Update package prep script to do async process execution and emit output as it happens. (#13918)"
This reverts commit b7169c1d951aa188c1cdc3b980e257e8a92f8abe.
