 6 | => Create a keystore
 7 | If you have an existing keystore, skip to the next step. If not, create one by running the following at the command line:
 8 | 
 9 | On Mac/Linux, use the following command:
10 | 
11 | content_copy
12 | keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key
13 | 
14 | On Windows, use the following command:
15 | 
16 | content_copy
17 | keytool -genkey -v -keystore c:/Users/USER_NAME/key.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias key
18 | 
19 | or also you can generate keystore from android studio just open your flutter project android folder inside the android studio and wait till build 
20 | not successed and then tap on BUILD and Generate signed bundle and apk and fill up all the thing
21 | 
22 | ****************************************************************************************************************************************

 4 |   => enter this command in termial 
 5 |  $ sudo gem install cocoapods
 6 |  $ pod setup
 7 |  //make sure that you have already specify version of ios in your general file.
 8 |  
 9 | 2. After that you have to refresh your xcode and build the app if there are something absence then you have to add into Podfile.lock
10 | Like example and repeat 1 step for get that package in pod
11 |   pod "BSImagePicker", "~> 2.8"
12 |   pod 'Firebase/Analytics'
13 |   pod 'Firebase/Core'
14 | 
15 | 3. moreever i got right now if your project with the firebase then you have to put  googleService-info.plist in Runner directory
16 | 
17 |   and enjoy ios

/flutter2.0:
--------------------------------------------------------------------------------
  1 | Flutter 2.0 
  2 | For null safely
  3 | Change sdk in pubspec 
  4 | Environment:
  5 |       sdk: ‘>2.12.0 <3.0.0’
  6 | 
  7 | Without null safely (Normal project)
  8 | Environment:
  9 |       sdk: ‘>2.7.0 <3.0.0’
 10 | 
 11 | 
 12 | 
 13 | 
 14 | Command for migrate our project to null safely
 15 | dart migrate
 16 | 
 17 | Command for Migrate, check and  update latest version in pubspec 
 18 | dart pub outdated --mode=null-safety
 19 | flutter pub upgrade --major-versions
 20 | dart migrate --skip-import-check
 21 | 
 22 | Command for update flutter inside your project .flutter
 23 | sh flutterw upgrade
 24 | 
 25 | 
 26 | 
 27 | 
 28 | 
 29 | String  => Non nullable  => You can’t pass null inside a non nullable variable , and if you still try to pass null value inside it then the dart compiler will show AOT compile time error warning.
 30 | Ex: String name;
 31 | 
 32 | String? => Nullable String  => You can pass null or value inside it but you must have to apply condition before using nullable string
 33 | Ex: String? name
 34 | 
 35 | Late => define later => If you will declare variable in the class and that variable init later then you must have to use late keyword before variable name
 36 | Ex: late String name;
 37 | 
 38 | 
 39 | !  =>  When the variable type is nullable and if the value might come null in the variable and still you wanna accept it then you can use ! after variable name.
 40 | Example:
 41 | String? name;
 42 | Text(name!);  //When you will put ! after variable name then compiler will remove warning error
 43 | 
 44 | There are many ways to handle nullable things instead of ! operator
 45 | 1. Hard If Else condition
 46 |     Example :
 47 |       String? name;
 48 |       if(name != null)
 49 |       {
 50 |            Text(name);
 51 |       }
 52 | 
 53 | 2. ?? operator
 54 | Example :
 55 |    String? name;
 56 |    Text(name??’test’);
 57 | 
 58 | 
 59 | 3. ! Operator
 60 | Example :
 61 | String? name;
 62 |    Text(name!);  // It will ignore null check cause You are using ! operator
 63 | 
 64 | 
 65 | 
 66 | 
 67 | 
 68 | 4. ?. Operator
 69 | Example
 70 | Class A{
 71 |      String? a;
 72 |      String? b;
 73 | A(this.a,this.b)
 74 | }
 75 | A a = A(null,”textB”)
 76 | 
 77 | Text(a?.a??’-’);
 78 | Text(a?.b??’-’);
 79 | 
 80 | 
 81 | 
 82 | 
 83 | 
 84 | 
 85 | Full Code Example
 86 | 
 87 | import 'dart:math';
 88 | void main() {
 89 |   Person a = Person(name: "hardik",facSport: "volly");
 90 |   Person b = Person(name: "aes",facSport: "cricket");
 91 |   Person c = Person(name: "hello",facSport: null,);
 92 |   Person d = Person(name: "aes",);
 93 |   
 94 |   func(String name){
 95 |   print("Problem "  + name);
 96 |   }
 97 |   
 98 |   String? currentName;
 99 |   if(currentName != null){
100 |     func(currentName);
101 |   }else{
102 |   }
103 |   
104 |   func(currentName??'null hato');
105 |   func(currentName!);
106 |   
107 |   //define later
108 |   late String currentUserName;
109 |   if(Random().nextBool()){
110 |     currentUserName = "Hardik kUmbhani";
111 |   }
112 |   
113 |   print("random" + currentUserName);
114 |   
115 | }
116 | 
117 | class Person{

120 | final String? facSport;
121 | Person({required this.name,this.facSport});

/null aware.dart:
--------------------------------------------------------------------------------
 1 | https://medium.com/@thinkdigitalsoftware/null-aware-operators-in-dart-53ffb8ae80bb
 2 | This is an updated version of Seth Ladd’s blog post about Null-aware operators in Dart. Most of the content is unchanged with the exception of the examples provided at the end of the post, which help make the post easier to understand.
 3 | Null-aware operators in dart allow you to make computations based on whether or not a value is null. It’s shorthand for longer expressions.
 4 | 
 5 | ??
 6 | Use ?? when you want to evaluate and return an expression IFF another expression resolves to null.
 7 | exp ?? otherExp
 8 | is similar to
 9 | ((x) => x == null ? otherExp : x)(exp)
10 | ??=
11 | Use ??= when you want to assign a value to an object IFF that object is null. Otherwise, return the object.
12 | obj ??= value
13 | is similar to
14 | ((x) => x == null ? obj = value : x)(obj)
15 | ?.
16 | Use ?. when you want to call a method/getter on an object IFF that object is not null (otherwise, return null).
17 | obj?.method()
18 | is similar to
19 | ((x) => x == null ? null : x.method())(obj)
20 | You can chain ?. calls, for example:
21 | obj?.child?.child?.getter
22 | If obj, or child1, or child2 are null, the entire expression returns null. Otherwise, getter is called and returned.
23 | Update [4/19/2019] — Dart 2.3
24 | ?…
25 | Dart 2.3 brings in a spread operator (…) and with it comes a new null aware operator, ?... !
26 | Placing ... before an expression inside a collection literal unpacks the result of the expression and inserts its elements directly inside the new collection.
27 | So now, these two are equivalent.
28 | List numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
29 | and
30 | List lowerNumbers = [1, 2, 3, 4, 5];
31 | List upperNumbers = [6, 7, 8, 9, 10];
32 | List numbers = […lowerNumbers…upperNumbers];
33 | To benefit from the new null aware operator, you can use it like this.
34 | List lowerNumbers = [1, 2, 3, 4, 5];
35 | List upperNumbers = [6, 7, 8, 9, 10];
36 | List numbers = […lowerNumbers?…upperNumbers];
37 | which is the equivalent to
38 | List numbers = [];
39 | numbers.addAll(lowerNumbers);
40 | if(upperNumbers != null){
41 |  numbers.addAll(upperNumbers);
42 | }
