What steps will reproduce the problem?

  1. Visit http://www.dartlang.org/docs/getting-started/
  2. Move pointer over the (|>) start button, notice callout "Run (Ctrl-Alt-R)"
  3. Press Ctrl-Alt-R and notice as nothing happens.
  4. Click in the source code textarea and notice how Ctrl-Alt-R now works.

What is the expected output? What do you see instead?

I expected the keyboard shortcut to work as advertized, without having to set focus in the textarea.

If this is not feasible, then the callout should only advertize the shortcut when applicable, i.e. focus is inside the textarea.

What version of the product are you using? On what operating system?

Above URL as of this issue submit time.

Please provide any additional information below.

Good catch, but not worth fixing as it's most useful when you're in the text box, anyway.


Added Component-Docs, WontFix labels.

Here's a minimal repro that this CL fixes:

`ui.dart`

```dart
library dart.ui;

import 'dart:ffi';

part 'foo.dart';
```

`foo.dart`

```dart
part of dart.ui;

@Native<Void Function()>(symbol: 'foo_func', isLeaf: true)
external void foo_func();
```

When compiling with `compile_platform.dart` with `--target=dart2wasm`, the following error appears:


```
Unhandled exception:

The issue seems to be that after doing this native transformation, the node's `fileUri` references the enclosing library (`ui.dart` above), but the `node.location` references the actual source file (`foo.dart` above) indirectly through `node.fileOffset`.

This ends up being an issue when compiling the platform dill in Google3,   but I didn't look into why `flutter build web --wasm` isn't broken.
