Features

Add several type of inputs to flutter_form_builder

Inputs

The currently supported fields include:

FormBuilderColorPicker - Input for Color selection
FormBuilderRating - For selection of a numerical value as a rating
FormBuilderSearchableDropdown - Field for selecting value(s) from a searchable list
FormBuilderSignaturePad - Field with drawing pad on which user can doodle
FormBuilderTouchSpin - Selection of a number by tapping on a plus or minus icon
FormBuilderTypeAhead - Auto-completes user input from a list of items

Parameters

In order to create an input field in the form, along with the label, and any applicable validation, there are several attributes that are supported by all types of inputs namely:

Attribute	Type	Default	Required	Description
`name`	`String`		`Yes`	This will form the key in the form value Map
`initialValue`	`T`	`null`	`No`	The initial value of the input field
`enabled`	`bool`	`true`	`No`	Determines whether the field widget will accept user input.
`decoration`	`InputDecoration`	`InputDecoration()`	`No`	Defines the border, labels, icons, and styles used to decorate the field.
`validator`	`FormFieldValidator<T>`	`null`	`No`	A `FormFieldValidator` that will check the validity of value in the `FormField`
`onChanged`	`ValueChanged<T>`	`null`	`No`	This event function will fire immediately the the field value changes
`valueTransformer`	`ValueTransformer<T>`	`null`	`No`	Function that transforms field value before saving to form value. e.g. transform TextField value for numeric field from `String` to `num`
The rest of the attributes will be determined by the type of Widget being used.
