AdaptiveTextField class

An adaptive text field that automatically handles keyboard type switching and provides built-in UI for users to select different input types.

This widget eliminates the need to manually handle keyboard type logic in every input field by providing a complete solution out of the box.

Example usage:

AdaptiveTextField(
  controller: _controller,
  availableTypes: [
    TextInputType.text,
    TextInputType.number,
    TextInputType.emailAddress,
  ],
)

Constructors

AdaptiveTextField({Key? key, required TextEditingController controller, List<TextInputType>? availableTypes, TextInputType? initialType, bool? showTypeSelector, bool obscureText = false, int? maxLines = 1, bool enabled = true, InputDecoration? decoration, String? validator(String?)?, dynamic onChanged(String)?, dynamic onTypeChanged(TextInputType)?, Map<TextInputType, String>? customLabels, List<TextInputFormatter>? inputFormatters})
const

Properties

availableTypes → List<TextInputType>?
List of available input types that users can select from. If null or empty, defaults to TextInputType.text.
final
controller → TextEditingController
Controls the text being edited in this text field.
final
customLabels → Map<TextInputType, String>?
Custom labels for each input type. If not provided, uses default labels.
final
decoration → InputDecoration?
Custom decoration for the text field.
final
enabled → bool
Whether the text field is enabled for user interaction.
final
hashCode → int
The hash code for this object.
no setterinherited
initialType → TextInputType?
Initial input type. If not specified, uses the first type from availableTypes.
final
inputFormatters → List<TextInputFormatter>?
Optional input formatters to apply to the text input.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
maxLines → int?
The maximum number of lines for the text field.
final
obscureText → bool
Whether to obscure the text being edited (e.g., for passwords).
final
onChanged → dynamic Function(String)?
Called when the value of the text field changes.
final
onTypeChanged → dynamic Function(TextInputType)?
Called when the input type changes.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
showTypeSelector → bool?
Whether to show the input type selector above the field. Defaults to true if more than one type is available.
final
validator → String? Function(String?)?
Validator function for form validation.
