Transcripts
to become a mobile app developer there
are five essential skills let's go over
them one by
one there are basically two ways to
build mobile apps native or
crossplatform with Native development we
can build an app that runs only on a
particular platform like iOS or Android
this approach gives us full control over
the capabilities of the target platform
resulting in great performance and the
best user experience however the
downside is that if you want to build
the same app for a different platform
form we have to create a separate
project in an entirely different
language and ecosystem this means two
separate projects and two sets of bugs
to fix that's where crossplatform or
multiplatform development comes to the
rescue with crossplatform development we
can reduce development Time by reusing
the same code for different platforms
and potentially reduce bugs fixing a bug
once means it's fixed across multiple
platforms now for Native development we
have a few options for iOS we can use
Objective C which is an older language
or Swift which is modern and preferred
for Android we can use Java which is a
traditional language or cotland which is
modern and preferred for crossplatform
development the option depends on the
framework or toolkit we use there are
several crossplatform toolkits like
react native flutter cotland
multiplatform Maui and a few others
let's dive into each one first off we
have react native which was released by
Facebook in 2015 this toolkit lets you
build mobile apps using JavaScript and
and react which is a popular library for
building web user interfaces some big
names using react native include
Microsoft Office scype and even Facebook
itself then we have flut which is a
Google product that came out in 2017
flut uses a programming language called
Dart which takes the best parts of
JavaScript Java and C some examples of
apps built with flutter are eBay Alibaba
and Google pay it's really powerful and
gaining a lot of traction now let's talk
about cotland multiplatform this is the
newest player released by jetbrains the
same company behind tools like intellig
pycharm and webstorm in my opinion the
best idees in the world it uses the
cotlin programming language which is a
modern language inspired by Java apps
like McDonald's Netflix and cash app are
built with cotton multiplatform finally
we have Maui which stands for net
multiplatform appui introduced by
Microsoft Maui allows you to build
native mobile and desktop apps using C
and . net these days most companies
prefer to use multiplatform development
to reduce their costs this means we can
rule out native development for now and
focus on cross-platform options now
which framework is the best well there
is no such a thing as the best framework
yes there are people out there like our
Superstar highly opinionated developer
Mr John Smith who swears by react native
but there are others with a different
opinion the reality is that neither of
these Frameworks is perfect each has its
own problems and quirks that you you
will discover once you start building
real applications Beyond YouTube
tutorials and the reason for that is
that they try to support two entirely
different platforms at the same time so
which crossplatform solution should you
choose well it depends on two things
first on what languages and Technologies
you're familiar with for example if
you're a c developer Maui might be the
easier route if you know web
Technologies like JavaScript and react
you might want to go for react native
it's an easier transition from web to
mobile development the other factor is
job opportunities there are often more
jobs available for react native and
flutter here you can see the number of
open positions for different types of
mobile app developers in the US now this
is the current situation here and maybe
different where you live maybe there are
more job opportunities for a flutter
developer so I recommend doing your own
research rather than taking my or
someone else's advice about which route
to choose but realistically if you're
looking for a career in Mobile
development you would have to choose
between react native and flutter if you
have basic web development skills react
native is a better route otherwise I
would recommend flutter because Dart
which is the programming language that
flutter uses is a nicer language to work
with than JavaScript it's more modern
and doesn't have the quirks and weird
Parts you find in JavaScript so decide
between JavaScript or Dart and commit to
a study plan I believe if you dedicate 3
to 5 hours every day you can learn the
essence of either of these languages in
about 2 months to help you on this
journey I've created a free
supplementary PDF that breaks down the
specific Concepts you need to learn for
each skill it also includes several
project ideas to help you practice and
apply what you have learned it's a great
resource to review your progress find
gaps in your knowledge and prepare for
interviews you can find the link in the
description Box by the way I have a
bunch of tutorials on this channel and
complete courses on my website if you're
looking for structur learning again
links are in the description box the
next thing you need to learn is a
Version Control System them like git git
is not a programming language it's a
tool we use to track changes to our code
and collaborate with others git and
GitHub which is a platform that hosts
git repositories are essential for every
developer now git has a ton of features
but you don't need to know them all for
everyday use think of it like the 8020
rule 80% of the time you use 20% of
git's features 1 to two weeks of
practice is enough to get up and running
now building mobile apps often involves
working with data structures and
implementing complex algorithms this is
where a lot of self-taught programmers
struggle because they try to skip ahead
and learn more and more languages and
tools without learning the fundamentals
of computer science data structures and
algorithms are critical subjects taught
to computer science students and they're
often covered in Tech interviews
especially at big companies like apple
Google and Microsoft while you can skip
this step and go to the next as someone
who has had the privilege of teaching
millions of people I highly recommend
you not to overlook this step otherwise
you're going to feel the pain later in
your career so spend 1 to 2 months
studying classic data structures and
algorithms this will give you a strong
foundation in programming and problem
solving the next thing I would recommend
learning which again a lot of
self-taught developers Miss is design
patterns design patterns are proven
solutions to Common software design
problems there are 23 classic design
patterns documented in the book design
patterns by the gang of four many of
these patterns are used in Mobile
Frameworks so learning them will give
you a deeper understanding of
object-oriented design principles and
how these mobile Frameworks work under
the hood now I have to tell you this
book is pretty old and written in C++
honestly it's a difficult read because
many of the examples in the book are dry
and not quite relevant to Modern
software that's why I've created a very
Hands-On and pragmatic course on this
topic where I use Java and modern
examples found in applications we use
every day you can see how design
patterns are used to solve problems in
modern applications whether you want to
take my course or use a different
resource I believe if you dedicate a few
hours every day you can have a pretty
solid understanding of design patterns
in about 2 months all right the next
thing you need to learn is a mobile
framework which we talked about before
for Dart you should learn flutter and
for JavaScript you should learn react
native assuming you have a solid
background in programming you can learn
either of these Frameworks in about 2
months so if you dedicated a few hours
every day and follow this road map
you'll have the necessary knowledge to
apply for an entry-level mobile
developer job in about 8 to 12 months if
you have any questions please let me
know in the comments below I'll do my
best to answer you right here or in my
future videos If you enjoyed this video
