/**
* A Pine Theme input field
*
* This supports prefixes and suffixes - separate boxes not part of the actual input field but used to convey extra
* information, such as a label, along with a leading and trailing icon - elements that are within the bounds of the input
* field content and is affected by [contentPadding]
*
* @param value current value of the input field
* @param onValueChanged handler that is called when the input value is changed
* @param modifier modifier to apply to the input field
* @param placeholder placeholder content to use when [value] is [blank][String.isBlank]
* @param prefix content to place at the start of the input field, but not within the actual field content itself
* @param leadingIcon content to place within the bounds of the input field at the start
* @param trailingIcon content to place within the bounds of the input field at the end
* @param suffix content to place at the end of the input field, but not within the actual field content itself
* @param colors colors to apply to the input field in various states
* @param interactionSource interaction source used to emits events
* @param contentPadding padding of the main content within the input field
* @param enabled whether the input field is enabled and responds to input events
* @param readOnly whether the input field is read only
* @param placeholderStyle text style to use for [placeholder]
* @param textStyle text style to use for [value]
* @param keyboardOptions software keyboard options that contains configuration such as KeyboardType and ImeAction.
* @param keyboardActions when the input service emits an IME action, the corresponding callback is called. Note that this IME action may be different from what you specified in KeyboardOptions.imeAction.
* @param singleLine when set to true, this text field becomes a single horizontally scrolling text field instead of wrapping onto multiple lines. The keyboard will be informed to not show the return key as the ImeAction. maxLines and minLines are ignored as both are automatically set to 1.
* @param maxLines the maximum height in terms of maximum number of visible lines. It is required that 1 <= minLines <= maxLines. This parameter is ignored when singleLine is true.
* @param minLines the minimum height in terms of minimum number of visible lines. It is required that 1 <= minLines <= maxLines. This parameter is ignored when singleLine is true.
* @param visualTransformation the visual transformation filter for changing the visual representation of the input. By default no visual transformation is applied.
