Widgets #
There are three primary widgets:

WearShape: Determines the shape of the watch face, whether it is square or round.
WearMode: Determines the current mode of the watch (Active Mode or Ambient Mode). The widgets inside it rebuilds whenever the mode changes.
WearInheritedShape: It can be used for passing the shape of the watch down the widget tree.

import 'package:flutter/material.dart';
import 'package:flutter_wear/mode.dart';
import 'package:flutter_wear/shape.dart';
import 'package:flutter_wear/wear_mode.dart';
import 'package:flutter_wear/wear_shape.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
Color _containerColor;
Color _textColor;

@override
void initState() {
super.initState();

_containerColor = Colors.white;
_textColor = Colors.black;
}

@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: WearShape(
builder: (context, shape) => WearMode(builder: (context, mode) {
if (mode == Mode.active) {
_containerColor = Colors.white;
_textColor = Colors.black;
} else {
_containerColor = Colors.black;
_textColor = Colors.white;
}
return Container(
color: _containerColor,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Row(),
FlutterLogo(size: 100),
Text(
'Shape: ${shape == Shape.round ? 'round' : 'square'}',
style: TextStyle(color: _textColor),
