Fitted TextField Container

A Container that automatically resizes it's width to fit the containing TextField's text value.

Usage

FittedTextFieldContainer

Param	Default	Description
textField		The TextField to contain

Example

FittedTextFieldContainer(
    textField: TextField(
        style: TextStyle(fontSize: 48),
        keyboardType: TextInputType.numberWithOptions(decimal: true),
        textAlign: TextAlign.right,
        decoration: InputDecoration(
            prefixText: "£",
            hintText: "0",
        ),
    ),
)

Here I've used hintText: "0" to keep the textfield from becoming very narrow when the TextField is empty.

AnimatedFittedTextFieldContainer

Param	Default	Description
growDuration	Duration(milliseconds: 300)	Duration to animate the container's width when text is longer
shrinkDuration	Duration(milliseconds: 600)	Duration to animate the container's width when text is shorter
growCurve	Curves.easeOutCirc	The curve to use in the grow animation
shrinkCurve	Curves.easeInCirc	The curve to use in the shrink animation
textField		The TextField to contain

Example

AnimatedFittedTextFieldContainer(
    growDuration: Duration(milliseconds: 300),
    shrinkDuration: Duration(milliseconds: 600),
    growCurve: Curves.easeOutCirc,
    shrinkCurve: Curves.easeInCirc,
    textField: TextField(
        style: TextStyle(fontSize: 48),
        keyboardType: TextInputType.numberWithOptions(decimal: true),
        textAlign: TextAlign.right,
        decoration: InputDecoration(
            prefixText: "£",
            hintText: "0",
        ),
    ),
)

Again, hintText: "0" helps to keep the textfield from becoming very narrow when the TextField is empty.
