HttpWidget<T> class
HttpWidget is a ready to use future builder of BaseHttp api calls.
loader shows loading while data is fetched.
errorWidget shows Error when there is some data in fetching.
builder is shown when data is fetched successfully.
Specify your api i.e Future function in api field.
Specify your apiURL in apiURL inorder to use cache functionality.
useCache is used to get data from cache for get directly from API.
set it true
to get data from cache and vica versa.
errorOrEmptyCondition is used to specify certain condition when an error is occurred or data is empty. errorWidget will be shown if condition is true.
onData will returns the data when there is data in cache or after api request. It will be called twice i.e once when getting data from cache & 2nd time after getting from api request.
