Swap out the moon emoji used for progress spinner for a single-cell character.

The moon emoji looked cool, but couldn't be used because of bugs in xterm.js, used for VSCode's terminal, among others. The moon emoji is two character cells wide, but xterm.js doesn't advance by two cells when it adds the emoji, but does go back by two when it backspaces.

This changes us to a different character animation (dots) that is only one cell wide, and so doesn't have this problem.

This reverts commit 61cf946b.

* Make CupertinoApp and MaterialApp both use WidgetsApp for Navigator

* Make CupertinoApp and MaterialApp const constructors

* Make WidgetsApp routes aware

* Update tests

This will now make it so that the Dart VM class returns any Isolate that
matches the passed Pattern, without checking for any specific strings
like "main()"

This causes the search to skip over Isolates that would have matched.

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
