Login system problems

When I try to login after clicking a button with firedb I need to click it three times


the problem-

please help
thank you

See your block.. How logical sequence is irrelevant ..

You must set like this.

If the text boxes are not empty then call tag list

After getting tag list
Check the username is exist in this list or not

If not then call firebase value for password

After getting firebase value then check password match.

If match go to next elsr just show alert

Your problem is, upon every click your app doing one by one. First click get tag list second click get the password and on third click only checking taglist anf pwd match. You must set events to be in order


No I dont get it could please tell me in more detail?
