Error while creating weather app WeatherProvider

Runtime Error
Can’t resolve all parameters for WeatherProvider: (?).

Please help me how to resolve this error

hello,

without code it is often difficulty to help.

In your case you call anywhere your weatherprovider, but use it without the correct amout of parameters, like

constructor(Location: string, time: string, burninhell: boolean)

and call it anywhere
this.myweatherprovider(mumbai, 01.01.2019)
and forgot to specify if the end of the world is near.

Best regards, anna-liebt
