There are still a number of problems with the search feature, but at least it doesn't crash after this CL. R=eseidel@chromium.org Review URL: https://codereview.chromium.org/1179643004.
SKY SDK
Sky and Sky's SDK are designed as layered frameworks, where each layer depends on the ones below it but could be replaced wholesale.
The bottom-most layer is the Sky Platform, which is exposed to Dart
code as the dart:sky package.
Above this are the files in the painting/ directory, which provide APIs related to drawing graphics.
Layout primitives are provided in the next layer, found in the
rendering/ directory. They use dart:sky and the
APIs exposed in painting/ to provide a retained-mode layout and
rendering model for applications or documents.
Widgets are provided by the files in the widgets/ directory, using a reactive framework.
Text input widgets are layered on this mechanism and can be found in the editing2/ directory.
