OudsDigitInput class
A purely visual widget that renders a single digit cell of a PIN code input.
Keyboard input is handled entirely by the parent OudsPinCodeInput via a single hidden TextField; displayValue is simply passed down for rendering.
Visual states
| Condition | Content shown |
|---|---|
| Not focused, empty | Hint placeholder |
| Not focused, filled | Value (● when hiddenPassword is true) |
| Focused, empty | Blinking cursor |
| Focused, filled — normal mode | Blinking cursor only |
| Focused, filled — accessibility mode | Value + blinking cursor |
The last row applies when isAccessibilityActive is true, giving
assistive-technology users a clear indicator that the cell is selected even
after it has been filled.
Example
// Typically created by OudsPinCodeInput — shown here for illustration.
OudsDigitInput(
index: 0,
isFocused: true,
displayValue: '3',
isAccessibilityActive: false,
digitInputDecoration: OudsDigitInputDecoration(
hintText: '-',
hiddenPassword: true,
),
)
Parameters:
- index: Zero-based position of this cell in the PIN sequence.
- isError: When
true, the cell adopts the error visual style. - isFocused: Whether this cell is the currently active position.
- displayValue: Character to display; empty string when the cell is empty.
- digitInputDecoration: Decoration options (hint, masking, style, …).
