flutter_dialpad

A phone dialer widget that can be added to any Flutter Application to enable the ability to dial a number. This could be combined with a VoIP application to enable placing calls.

This is a purely Dart widget with no dependency on Android or iOS except for the flutter_dtmf package it uses for DTMF tone generation on pressing a button. You can turn it off by setting enableDtmf: false

Getting Started

@override  
  Widget build(BuildContext context) {  
    return Scaffold(  
      backgroundColor: Colors.black,  
      body: SafeArea(  
        child:  
            DialPad(  
                // temporarily disabled  
                // enableDtmf: true,  
                outputMask: "(000) 000-0000",  
                backspaceButtonIconColor: Colors.red,  
                makeCall: (number){  
                    print(number);  
                }  
            )  
        ),  
    );  
  }  

Pre-built UIs

Support has been added for custom UIs, using Dialpad.ios for iOS style keypad or DialPad.metro metro theme. Additional customization is available with many different options.

UI Scaling

A few considerations:

ScalingType

DialPad supports dynamic scaling of UI. Using either a ScalingType.fixed approach will use preset text & icon sizes. If you are using flutter_web_frame with some window constraints, you may wish to use ScalingType.height. For most cases ScalingType.min should suffice.

ScalingSize

Scaling Size provides an easy way to specify the scalar multiplier for the scaling calculation. Instead of using a predefined value of e.g. 0.001, the ScalingSize.small is now used. Customization for buttons allows making the dial button large with a small backspace button.

Scalable

If you wish to add your own Scalable button, feel free to create a widget with Scalable to make use of the rescale function.

Clamping

Scaled UI elements may become extremely small, using minScalingSize and maxScalingSize you can clamp the scaling to a percentage of the original size. This is useful for ensuring the UI is still usable.
