flutter_cross_platform 0.1.4

The Cross Platform provides mixins to simple decide which widget should be built.

example/example.dart

// Allows to split widget into 'device' and 'web' variants
import '../lib/flutter_cross_platform.dart';
import 'package:flutter/material.dart';

class PlatformSplitted
  extends StatelessWidget
  with PlatformSplitMixin {

  @override
  Widget build(BuildContext context) {
    // You can pass any data to each variant builder

    // will return green container with platform specific text
    return platformVariant(context, data: Colors.green);
  }

  @override
  Widget device(context, {data}) {
    return Container(
      color: data as Color,
      child: Center(
        child: Text("I'm device variant")
      ),
    );
  }

  @override
  Widget web(context, {data}) {
    final color = data as Color;
    return Container(
      color: color,
      child: Center(
        child: Text("I'm web variant")
      ),
    );
  }
}


// Similar to previous mixin but initialize variants only once. Useful, for example, to override navigation.
class MyApplication
  extends StatelessWidget
  with PlatformSplitSingletonMixin {

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: "MyApplication",
      builder: (context, child) {

        // Initialise singletons outside widgets
        // So they will not rebuild
        initPlatforms(context);
        return platformVariant;
      },
    );
  }

  @override
  Navigator web(context) {
    return Navigator();
  }

  @override
  Navigator device(context) {
    return Navigator();
  }
}
