Properties#
semantics_label
#
semantics_label: str | None = None
An alternative semantics label for this text.
If present, the semantics of this control will contain this value instead of the actual text.
Raises:
-
ValueError
–If
semantics_label
is set whentext
isNone
.
spans
#
Additional spans to include as children.
Note
If both spans
and text
are defined,
the text
takes precedence.
spell_out
#
spell_out: bool | None = None
Whether the assistive technologies should spell out this text character by character.
If the text is 'hello world', setting this to true causes the assistive technologies, such as VoiceOver or TalkBack, to pronounce 'h-e-l-l-o-space-w-o-r-l-d' instead of complete words. This is useful for texts, such as passwords or verification codes.
If this span contains other text span children, they also inherit the property from this span unless explicitly set.
If the property is not set, this text span inherits the spell out setting from its parent. If this text span does not have a parent or the parent does not have a spell out setting, this text span does not spell out the text by default.

#
text: str | None = None

event callback is provided,
it is fired after that.
Events#
on_enter
