Creates a basic text input control.

The maxLines property can be set to null to remove the restriction on the number of lines. By default, it is one, meaning this is a single-line text field. maxLines must be null or greater than zero.

If keyboardType is not set or is null, its value will be inferred from autofillHints, if autofillHints is not empty. Otherwise it defaults to TextInputType.text if maxLines is exactly one, and TextInputType.multiline if maxLines is null or greater than one.

The text cursor is not shown if showCursor is false or if showCursor is null (the default) and readOnly is true.

The controller, focusNode, obscureText, autocorrect, autofocus, showSelectionHandles, enableInteractiveSelection, forceLine, style, cursorColor, cursorOpacityAnimates,backgroundCursorColor, enableSuggestions, paintCursorAboveText, selectionHeightStyle, selectionWidthStyle, textAlign, dragStartBehavior, scrollPadding, dragStartBehavior, toolbarOptions, rendererIgnoresPointer, readOnly, and enableIMEPersonalizedLearning arguments must not be null.
