`CameraAwesomeBuilder.custom.builder` doesn't rebuild when state changes

[Zazo032]

Steps to Reproduce

Run this small sample:

CameraAwesomeBuilder.custom(
  enableAudio: false,
  saveConfig: SaveConfig.photo(
    pathBuilder: () => photoPath,
  ),
  builder: (CameraState state) {
    return IconButton(
      color: Colors.white,
      icon: Icon(_getFlashIcon(state.sensorConfig.flashMode)),
      key: const Key('flash_icon'),
      onPressed: state.sensorConfig.switchCameraFlash,
    );
  }
),

Expected results

After tapping the IconButton, state.sensorConfig.switchCameraFlash gets called and a new FlashMode should be available in state.sensorConfig.flashMode. Also happens with state.sensorConfig.sensor after calling state.switchCameraSensor

Actual results

builder method is not called, so Icons are not updated.

Hello, thank you for reporting this! We might make the documentation more clear about this, but what you need to do is listen to the sensorConfig as well. The stream of the current sensorConfig is accessible by appending a $ to the end of the sensorConfig (sensorConfig$). This is how the built-in Flash button works:

StreamBuilder<SensorConfig>(
  stream: state.sensorConfig$,
  builder: (_, sensorConfigSnapshot) {
    if (!sensorConfigSnapshot.hasData) {
      return SizedBox();
    }
    final sensorConfig = sensorConfigSnapshot.requireData;
    return StreamBuilder<FlashMode>(
      stream: sensorConfig.flashMode$,
      builder: (context, snapshot) {
        // return your icon
      },
    );
  },
);

You should work with the sensorConfig$ if you want to get their updates.

StreamBuilder<SensorConfig> throws an error because it seems like SensorConfig class is not exposed

Similar thing happens to CameraPreviewFit, seems like there are a few hidden but required APIs:

As a workaround, you can import:

import 'package:camerawesome/src/layouts/awesome/widgets/awesome_camera_preview.dart';

But the following linter gets triggered: https://dart-lang.github.io/linter/lints/implementation_imports.html

I'll make a PR to expose these, you're right.

Classes should be exposed on master now. I'm closing the issue, feel free to open a new one if something else is missing. 👌
