Youā€™re trying to use FormGroup but you are missing either importing it or injecting the provider inside the constructor, without checking out your code is hard to tell.

create.ts file

import { Component } from '@angular/core';
import { IonicPage, NavController, Loading, LoadingController,NavParams } from 'ionic-angular';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import { AngularFireAuth } from 'angularfire2/auth';


@Component({
  selector: 'page-create',
  templateUrl: 'create.html',
})
export class CreatePage {

  constructor(public navCtrl: NavController,  public signupForm:FormGroup,
public loading:Loading,public navParams: NavParams,public loadCtrl: LoadingController, 
public formBuilder: FormBuilder, public afAuth: AngularFireAuth) {


   this.signupForm = formBuilder.group({
    email: ['', Validators.required],
    password: ['', Validators.compose([Validators.minLength(6), Validators.required])]
  });

}
signupUser(){
  if (!this.signupForm.valid){
    console.log(this.signupForm.value);
  } else {
    this.afAuth.auth.createUserWithEmailAndPassword(this.signupForm.value.email, this.signupForm.value.password)
    .then(() => {
      this.loading.dismiss().then( () => {
        this.navCtrl.setRoot('HomePage');
      });
    }, (error) => {
      this.loading.dismiss().then( () => {
        console.error(error);
      });
    });
    this.loading = this.loadCtrl.create();

In this way I am able to share one record ,but now I want to enable multiple selections,like If I have 5 books ,I am able to share now one book at a timeā€¦but how to select multiple books at a time and push it to other user in the same way,as we are sharing a single file at a timeā€¦

Firebase uses WebSockets and MongoDB for real-time database management. They are powerful and offer total control across the database - Contus Fly Chat kit

Thanks for the Information,
Appreciate it.
I used firebase cloud functions to solve it.
