* PointerEvent.local* properties are calculated lazily; other properties are delegated to original.
* Transformed PointerEvent becomes a subclass of its original class.

No matter what level(error, warning, info) issues flutter analyze always return fatal exit code(1). CI/CD environment receive 1(!0). This may leads to e.g. Jenkins Build step 'Execute shell' marked build as failure.
I propose according to AnalysisSeverity level return fatal(1) or success(0) exit code.

* Dispose of images after using them
Adds ImageInfo.clone, ImageInfo.dispose, and ImageInfo.isCloneOf.
Makes all stateful holders of ui.Image objects properly clone and dispose of them.
Behavior change for ImageStreamCompleter: Removing the last listener after registering at least one listener results in the object being disposed, and new listeners cannot be added, unless a keepAlive handle is created.
Makes all non-stateful holders of ui.Image (i.e. paintImage and RawImage) assert that whoever gave the image to them has not disposed it on them.

* migrate some material files to nullsafety

* fix test_private

* address review comments

* fix private test on windows

package:http can throw a ClientException, which the crash reporter must catch or the tool will crash in the crash reporter. 3/4 crash on dev.

Continued gradual rollout - dev is not that much riskier than master but will give much more data
