StaticLayout is a Layout for text that will not be edited after it
is laid out. Use DynamicLayout
for text that may change.
This is used by widgets to control text layout. You should not need
to use this class directly unless you are implementing your own widget
or custom display object, or would be tempted to call
Canvas.drawText()
directly.

no ellipsis is to take place.
| |||||||||||
Return the offset of the first character to be ellipsized away,
relative to the start of the line.

getWidth() if it is not doing anything special. | |||||||||||
Returns whether the specified line contains one or more
characters that need to be handled specially, like tabs
or emoji.
| |||||||||||
Return the number of lines of text in this layout.

Returns the number of extra pixels of descent padding in the bottom line of the Layout.
Returns the number of characters to be ellipsized away, or 0 if no ellipsis is to take place.
Return the offset of the first character to be ellipsized away, relative to the start of the line. (So 0 if the beginning of the line is ellipsized, not getLineStart().)
Return the width to which this Layout is ellipsizing, or
getWidth()
if it is not doing anything special.
Returns whether the specified line contains one or more characters that need to be handled specially, like tabs or emoji.
Return the descent of the specified line(0…getLineCount() - 1).
Returns the directional run information for the specified line. The array alternates counts of characters in left-to-right and right-to-left segments of the line.
NOTE: this is inadequate to support bidirectional text, and will change.
Get the line number corresponding to the specified vertical position. If you ask for a position above 0, you get 0; if you ask for a position below the bottom of the text, you get the last line.
Return the text offset of the beginning of the specified line ( 0…getLineCount()). If the specified line is equal to the line count, returns the length of the text.
Return the vertical position of the top of the specified line (0…getLineCount()). If the specified line is equal to the line count, returns the bottom of the last line.
Returns the primary directionality of the paragraph containing the
specified line, either 1 for left-to-right lines, or -1 for right-to-left
lines (see DIR_LEFT_TO_RIGHT
, DIR_RIGHT_TO_LEFT
).
Returns the (negative) number of extra pixels of ascent padding in the top line of the Layout.
