Text vertical alignment is a common complaint and one of the most common
causes is different type faces being used in the same paragraph (for
instance, when there's English / Arabic in the same paragraph so the
default font doesn't contain the required glyphs for some characters).
Hopefully this flag is going to make debugging alignment issues a bit
easier, and in some github issues attaching screenshots with the flag on
will be helpful for diagnosing the issue.
### What the layout boxes look like
```dart
final testText =
'Quick brown fox, نص, trailing spaces${" " * 100}'
'new line at the end.\n\n\n\n';
Column([
Text(testText, style: TextStyle(height: kTextHeightNone)),
Text(testText, style: TextStyle(height: 1.0)),
Text(
testText,
style: TextStyle(height: kTextHeightNone),
strutStyle: StrutStyle(fontSize: 30),
),
])
```
