StreamTextInput class

A text input styled for the Stream design system.

StreamTextInput provides a custom text input container with outline borders, optional leading/trailing widgets, and animated helper text.

The field supports both controlled (via controller) and uncontrolled (via initialValue) modes. At most one may be provided; if neither is given, an internal controller is created automatically.

Visual properties are resolved in order:

  1. Per-instance style overrides
  2. StreamTextInputTheme from the widget tree
  3. Design token fallbacks from StreamColorScheme and StreamTextTheme

{@tool snippet}

Basic text input with hint:

StreamTextInput(
  hintText: 'Enter your name',
  onChanged: (value) => print(value),
)

{@end-tool}

{@tool snippet}

Text input with error:

StreamTextInput(
  initialValue: 'bad input',
  helperText: 'This field is required',
  helperState: StreamHelperState.error,
  onChanged: (value) {},
)

{@end-tool}

{@tool snippet}

Controlled text input with leading icon:

StreamTextInput(
  controller: myController,
  leading: Icon(Icons.search),
  hintText: 'Search...',
)

{@end-tool}
