+/**
+ * A text field to input a query in a search bar.
+ *
+ * @param state [TextFieldState] that holds the internal editing state of the input field.
+ * @param onSearch the callback to be invoked when the input service triggers the
+ *   [ImeAction.Search] action. The current query in the [state] comes as a parameter of the
+ *   callback.
+ * @param expanded whether the search bar is expanded and showing search results.
+ * @param onExpandedChange the callback to be invoked when the search bar's expanded state is
+ *   changed.
+ * @param modifier the [Modifier] to be applied to this input field.
+ * @param enabled the enabled state of this input field. When `false`, this component will not
+ *   respond to user input, and it will appear visually disabled and disabled to accessibility
+ *   services.
+ * @param readOnly controls the editable state of the input field. When `true`, the field cannot
+ *   be modified. However, a user can focus it and copy text from it.
+ * @param textStyle the style to be applied to the input text. Defaults to [LocalTextStyle].
+ * @param placeholder the placeholder to be displayed when the input text is empty.
+ * @param leadingIcon the leading icon to be displayed at the start of the input field.
+ * @param trailingIcon the trailing icon to be displayed at the end of the input field.
+ * @param prefix the optional prefix to be displayed before the input text.
+ * @param suffix the optional suffix to be displayed after the input text.
+ * @param inputTransformation optional [InputTransformation] that will be used to transform
+ *   changes to the [TextFieldState] made by the user. The transformation will be applied to
+ *   changes made by hardware and software keyboard events, pasting or dropping text,
+ *   accessibility services, and tests. The transformation will _not_ be applied when changing
+ *   the [state] programmatically, or when the transformation is changed. If the transformation
+ *   is changed on an existing text field, it will be applied to the next user edit. The
+ *   transformation will not immediately affect the current [state].
+ * @param outputTransformation optional [OutputTransformation] that transforms how the contents
+ *   of the text field are presented.
+ * @param scrollState scroll state that manages the horizontal scroll of the input field.
+ * @param shape the shape of the input field.
+ * @param colors [TextFieldColors] that will be used to resolve the colors used for this input
+ *   field in different states. See [SearchBarDefaults.inputFieldColors].
+ * @param interactionSource an optional hoisted [MutableInteractionSource] for observing and
+ *   emitting [Interaction]s for this input field. You can use this to change the search bar's
+ *   appearance or preview the search bar in different states. Note that if `null` is provided,
+ *   interactions will still happen internally.
