Issue: Encountered undefined provider for ngx-material-timepicker

[joelduncan1]

npm: 6.5.0
node: 8.11.4
angular: 6.0.8

[ISSUE]
npm build:prod having an issue detecting ngx-material-timepicker have an undefined providers for version 2.11.1

[ALTERNATIVE]
I reverted my node module for ngx-material-timepicker to 2.8.4 and it works.

Can confirm. I am also getting the same error :
Encountered undefined provider! Usually this means you have a circular dependencies (might be caused by using 'barrel' index.ts files

Confirm too, with this errors (only with AOT compilation)

ERROR in : Unexpected value 'undefined' exported by the module 'NgxMaterialTimepickerModule in [...]/node_modules/ngx-material-timepicker/ngx-material-timepicker.d.ts'

ERROR in : Encountered undefined provider! Usually this means you have a circular dependencies. This might be caused by using 'barrel' index.ts files.

EDIT
This is probably due to your usage of barrel files, which you added in latest commit.
Barrel files are a bit tricky and it's probably better to avoid them intra-library.

Here you used ../models instead of the full references.

ngx-material-timepicker/src/app/material-timepicker/directives/ngx-material-timepicker-them.directive.spec.ts

Line 5 in 373d095

import {NgxMaterialTimepickerTheme} from '../models';

ngx-material-timepicker/src/app/material-timepicker/directives/ngx-material-timepicker-theme.directive.ts

Line 2 in 373d095

import {NgxMaterialTimepickerTheme} from '../models';

Or here you used them to import everything into the library module

ngx-material-timepicker/src/app/material-timepicker/ngx-material-timepicker.module.ts

Lines 5 to 22 in 373d095

	import {
	NgxMaterialTimepicker12HoursFaceComponent,
	NgxMaterialTimepicker24HoursFaceComponent,
	NgxMaterialTimepickerButtonComponent,
	NgxMaterialTimepickerDialComponent,
	NgxMaterialTimepickerDialControlComponent,
	NgxMaterialTimepickerFaceComponent,
	NgxMaterialTimepickerMinutesFaceComponent, NgxMaterialTimepickerPeriodComponent,
	NgxMaterialTimepickerToggleComponent
	} from './components';
	import {
	AutofocusDirective,
	NgxMaterialTimepickerThemeDirective,
	NgxMaterialTimepickerToggleIconDirective, OverlayDirective,
	TimepickerDirective
	} from './directives';
	import {MinutesFormatterPipe, StyleSanitizerPipe, TimeFormatterPipe} from './pipes';
	import {NgxMaterialTimepickerEventService, NgxMaterialTimepickerService} from './services';

The problem is probably in one (or more) of this imports

I confirm error disappears downgrading to 2.11.0

I also confirm the issue. Added a console.log('type', type) in the line 18783 of the file ngx-material-timepicker/src/app/material-timepicker/ngx-material-timepicker.module.ts and this popped up:

type { ngModule: StaticSymbol { filePath: 'C:/Users/admin/Projects/my-project/node_modules/ngx-material-timepicker/ngx-material-timepicker.d.ts', name: 'NgxMaterialTimepickerModule', members: [] }, providers: [ undefined, undefined ] }

I'll find out the problem and fix it in the next two days. Sorry for this.

[IlCallo]

No problem man, it's still open source stuff you give away for free.
Take your time, and thank you :)

[Agranom]

Fixed. Update to 2.11.2
