 * CurvedText is a component allowing developers to easily write curved text following
 * the curvature a circle (usually at the edge of a circular screen).
 * CurvedText can be only created within the CurvedLayout to ensure the best experience, like being
 * able to specify to positioning.
 * The default [style] uses the [LocalTextStyle] provided by the [MaterialTheme] / components,
 * converting it to a [CurvedTextStyle]. Note that not all parameters are used by [curvedText].
 * If you are setting your own style, you may want to consider first retrieving [LocalTextStyle],
 * and using [TextStyle.copy] to keep any theme defined attributes, only modifying the specific
 * attributes you want to override, then convert to [CurvedTextStyle]
 * For ease of use, commonly used parameters from [CurvedTextStyle] are also present here. The
 * order of precedence is as follows:
 * - If a parameter is explicitly set here (i.e, it is _not_ `null` or [TextUnit.Unspecified]),
 * then this parameter will always be used.
 * - If a parameter is _not_ set, (`null` or [TextUnit.Unspecified]), then the corresponding value
 * from [style] will be used instead.
 * Additionally, for [color], if [color] is not set, and [style] does not have a color, then
 * [LocalContentColor] will be used with an alpha of [LocalContentAlpha]- this allows this
 * [curvedText] or element containing this [curvedText] to adapt to different background colors and
 * still maintain contrast and accessibility.
 * For samples explicitly specifying style see:
 * TODO(b/283777480): Add CurvedText samples
 * For examples using CompositionLocal to specify the style, see:
 * TODO(b/283777480): Add CurvedText samples
 * For more information, see the
 * [Curved Text](
 * guide.
 * @param text The text to display
 * @param modifier The [CurvedModifier] to apply to this curved text.
 * @param background The background color for the text.
 * @param color [Color] to apply to the text. If [Color.Unspecified], and [style] has no color set,
 * this will be [LocalContentColor].
 * @param fontSize The size of glyphs to use when painting the text. See [TextStyle.fontSize].
 * @param fontFamily The font family to be used when rendering the text.
 * @param fontWeight The thickness of the glyphs, in a range of [1, 1000]. see [FontWeight]
 * @param fontStyle The typeface variant to use when drawing the letters (e.g. italic).
 * @param fontSynthesis Whether to synthesize font weight and/or style when the requested weight
 * or style cannot be found in the provided font family.
 * @param style Specifies the style to use.
 * @param angularDirection Specify if the text is laid out clockwise or anti-clockwise, and if
 * those needs to be reversed in a Rtl layout.
 * If not specified, it will be inherited from the enclosing [curvedRow] or [CurvedLayout]
 * See [CurvedDirection.Angular].
 * @param overflow How visual overflow should be handled.
