DebugTextFormatter is a text formatter for use in tests, correspondingly, it is defined in flame_test.
Compared to DebugTextPainterTextElement it has several advantages:
Does not depend on a TextPainter, and thus it is truly platform-independent;
Supports font-weight, font-style, and color.
DebugTextPainterTextElement and the debugMode in TextPainterTextFormatter are deprecated.
