android – Utilise capabilities throughout two Dart recordsdata

I am attempting to run a easy timer utilizing the timer_controller and timer_count_down libraries. I might just like the maintain the buttons in a separate file with a view to maintain the code clear, nevertheless when operating the primary app, the buttons not management the timer. I might prefer to know ‘import’ these capabilities so to talk.

I’ve searched a couple of methods and located quite a few sources, for instance utilizing
import ‘bundle:pattern/world.dart’; nevertheless, this did not appear to exist when coming into it into the dart file.

import 'bundle:flutter/materials.dart';
import 'bundle:timer_app/util/buttons.dart';
import 'bundle:timer_count_down/timer_controller.dart';
import 'bundle:timer_count_down/timer_count_down.dart';

class TimerTile extends StatefulWidget {
  const TimerTile({tremendous.key});

  @override
  State<TimerTile> createState() => _TimerTilesState();
}

class _TimerTilesState extends State<TimerTile> {
  remaining CountdownController _controller =
      new CountdownController(autoStart: false);

  @override
  Widget construct(BuildContext context) {
    return Column(
        mainAxisAlignment: MainAxisAlignment.heart,
        crossAxisAlignment: CrossAxisAlignment.heart,
        kids: [
          Container(
            padding: const EdgeInsets.symmetric(
              horizontal: 16,
            ),
            child: MyButtons(),
          ),
          Container(
              padding: const EdgeInsets.symmetric(
                horizontal: 16,
              ),
              child: Countdown(
                  controller: _controller,
                  seconds: 5,
                  build: (_, double time) => Text(
                        time.toString(),
                        style: TextStyle(
                          fontSize: 100,
                        ),
                      )))
        ]);
  }
}
