Fields

enabled: bool

focused: bool

focusable: bool

selected: bool

checked: Option<CheckedState>

expanded: Option<bool>

read_only: bool

editable: bool

obscured: bool

Whether a text field’s value is visually obscured (for example a password field). Keeping this in the portable tree lets native accessibility adapters make the same privacy decision as the widget layer without exposing the clear-text paint representation.

multiline: bool

selection: Option<TextSelection>

item_index: Option<usize>

set_size: Option<usize>

busy: bool

Indicates that the node’s value is still being produced.

invalid: bool

Validation state exposed independently from enabled/read-only state.

required: bool

Whether the user must provide a value.

numeric_value: Option<f64>

Numeric range/value metadata used by sliders, meters, and progress indicators. Values stay floating point because Flutter controls do.

numeric_min: Option<f64>

numeric_max: Option<f64>

numeric_step: Option<f64>

heading_level: Option<u8>

Heading level in the portable tree (1 is the most prominent level).
