TextComponentSpec

@MountSpec(isPureRender = true, poolSize = 30, canPreallocate = true, events = [TextOffsetOnTouchEvent::class])

Component to render text. See text-widget for more details.

Example Text usage:

final SpannableStringBuilder spannable = new SpannableStringBuilder();
spannable.setSpan(new StyleSpan(Typeface.BOLD), start, end, Spannable.SPAN_INCLUSIVE_INCLUSIVE);

Text.create(c)
  .text(spannable) // String can be used
  .textSizeDip(20)
  .maxLines(3)
  .ellipsize(TextUtils.TruncateAt.END)
  .textColor(Color.BLACK)
  .build()
