* add a test for single- and multi-line paragraph layout

* use flutter_test

* use closeTo for double comparison

This changes the compiler output for gradle to be less verbose and more easily read.

This only applies to compilation error messages: other gradle messages will continue to print as before.

It also fixes a small problem with the performance measurement printing (see that "7.1s" on it's own line in the original?) so that if something is expected to have multiple lines of output, it prints an initial line, and a "Done" line with the elapsed time, so that it's possible to know what the time applies to.

It also updates the spinner to be fancier, at least on platforms other than Windows (which is missing a lot of symbols in its console font).

Addresses #17307

This fixes a flaky test where it included 0ms as part of an output check. Kind of a classic flaky test.

Fix a link that works in GitHub but not in dartdoc.

Use "product" mode VM snapshot when running dynamic "release" mode flutter with cached engine. (#22043)

Dynamic "release" mode requires "product" (not "release") mode VM, so we must point it to the correct cached snapshot.

Generation and caching of this snapshot happens the following corresponding change: https://chromium-review.googlesource.com/c/chromium/tools/build/+/1232134

This is the follow-up to https://github.com/flutter/flutter/pull/20958.

This is a cleanup PR.

Closes #16031

This adds support to AnsiTerminal for colored output, and makes all tool output written to stderr (with the printError function) colored red.

No color codes are sent if the terminal doesn't support color (or isn't a terminal).

Also makes "progress" output print the elapsed time when not connected to a terminal, so that redirected output and terminal output match (redirected output doesn't print the spinner, however).

Addresses #17307

* Revert "Revert "Add RichText support to find.text" (#22046)"

This reverts commit 8e704219.

* Revert "Implement Double Tap Handling in TextField and Editable (#21264)"

This reverts commit 02e87334.

Thanks @NikoYuwono for getting this working! We appreciate your help!

* Implement Double Tap Handling in TextField and Editable

* Fix test broken by the change and add test for double tap

* Fix affected tests

* Remove unnecessary new

* Fix test

Fixes #21113.

This fixes the devicelab failure after #22006 renamed this command.

Renamed 'flutter materialize' to 'flutter make-host-app-editable'. The iOS version is still incomplete and will therefore require additional renaming. (#21771) (#22006)

Closes #18679

Xcode 10 introduces a new build system which includes stricter checks on
duplicate build outputs.

When plugins are in use, there are two competing build actions that copy
Flutter.framework into the build application Frameworks directory:

  1. The Embed Frameworks build phase for the Runner project
  2. The [CP] Embed Pods Frameworks build phase that pod install creates
     in the project.

Item (1) is there to ensure the framework is copied into the built app
in the case where there are no plugins (and therefore no CocoaPods
integration in the Xcode project). Item (2) is there because Flutter's
podspec declares Flutter.framework as a vended_framework, and CocoaPods
automatically adds a copy step for each such vended_framework in the
transitive closure of CocoaPods dependencies.

As an immediate fix, we opt back into the build system used by Xcode 9
and earlier. Longer term, we need to update our templates and
flutter_tools to correctly handle this situation.

This should fix #18889 which may be related to `adb logcat` not working correctly in non-terminals on some LG devices. See https://github.com/flutter/flutter/issues/18889#issuecomment-422217761.

Add back screenshot extension that was temporarily disabled.

Add matchesReferenceImage matcher to test that the screenshot extension
generates equivalent images to InspectorService.instance.screenshot.

This caused issues for projects without an Xcode workspace. Almost all
Flutter projects in the wild will have a workspace, but this patch needs
to add a check to catch any that lack one.
