WHAT IS FLUTTER ?

• Widget s are t he basic building blocks of a
Flut t er app’s user int erf ace.
• Each w idget is an immut able declarat ion of
part of t he user int erf ace. U nlike ot her
f ramew orks t hat separat e view s, view
cont rollers, layout s, and ot her propert ies,
Flut t er has a consist ent , unif ied object
model: t he w idget
• Widget s f orm a hierarchy based on
composition. Each w idget nests inside, and
inherit s propert ies f rom, it s parent .
EVERYTHING IS A
WIDGET

WIDGET TREE
• Widget tree is a structure
t hat represent s how our
w idget s are organiz ed. So,
as w e build our
application, composing
w idgets t o each ot her,
t his st ruct ure can grow.

SUPPORTED IDE's
• Most recommend IDE's for flutter are

• D art is an open - source, object -
orient ed, general - purpose
programming language developed by
Google in 2011.
• D art uses a ‘C ’ st yle synt ax and
opt ionally t ranscompiles int o
JavaScript .
• D art is also being used f or N at ive
and C ross - plat form mobile
development .
• It support s int erf aces, mixins,
abst ract classes.
WHAT IS DART?

• D art made t he biggest comeback f rom
2018 t o 2019, f rom being number one on
t he Worst Programming Language t o
Learn in 2018 t o 16t h place on t he list in
2 0 1 9 .
• Programming language popularit y list s
alw ays include basically t he same cast
of t he usual suspect s like Pyt hon, Java
and so on, but t he lat est IEEE Spect rum
ranking sees new comer D art debut ing at
No. 16.

• Flut t er provides a number of w idgets t hat help you
build apps t hat f ollow Mat erial D esign.
• A Mat erial app st art s w ith t he Mat erialA pp w idget,
w hich builds a number of usef ul w idget s at t he root of
your app, including a N avigat or, w hich manages a
st ack of w idgets ident if ied by st rings, also know n as
“ rout es” .
• The Navigator lets you transition smoothly betw een
screens of your applicat ion.
• Let s see some basic and commonly used w idgets.
SOME BASIC WIDGETS IN
FLUTTER

• To make the UI more interactive and attractive
w e have some advanced w idgets
• They are

• Gest ures can dispat ch
multiple events,
corresponding t o t he

UI -
Flutter apps look as good on the
up-to-date operating systems as they do on
older versions.
This means that your Flutter app will
look and behave naturally on each
platform, imitating their native
components.
Application components look just lik e native ones
(e.g. a button on an iOS device look s just lik e a
native iOS button, and the same on Android).
If you want your app to look near -identical across
platforms – as well as on older versions of an
operating system (as Flutter achieves) – then
consider using third -party libraries

TOP APPS MADE BY THIS TECHNOLOGY -

COMPETITIVE ADVANTAGE -
Great look and feel thanks to rich
widgets
Rapidly growing community, and
popularity
Excellent documentation with strong
support from the Flutter team (which
makes it easy to start developing
with Flutter)
Stability (5+ years on the market)
Many successful, prominent market players using
React Native;
Mature, vast community
Easy-to-learn technology;
Plenty of tutorials and libraries, which allow
quick and easy development

Web support is a code - compat ible implement at ion of
Flut t er t hat is rendered using st andards - based w eb
t echnologies: H TML, C SS and JavaScript .
Wit h w eb support , you can compile exist ing Flut t er
code w ritten in D art int o a client experience t hat can
be embedded in the brow ser and deployed to any w eb
server.
WEB SUPPORT TO FLUTTER

COMPANIES REACTIONS ON
FLUTTER
• With new advanced and customize UI many companies
are thinking to Switch on flutter, as flutter is cross
platform framework so there is no need to keep two
developer's team i.e for IOS and Android.
• Also managing the apps will be easier for updates.
• Using flutter developer's time will be save as they don't
need to build same apps for different platforms.
• There are many companies which have already adopted
flutter like..........

• As companies are tryIng to convert there native apps to
cross platform apps.
• So the demand of flutter developer will be increase.
• Also the google is coming with his new operating
system i.e FUCHSIA .
• People are predicting that Android may be get replace
by Fuchsia
• On Fuchsia operating system only the flutter apps can
be runned.
• So there is highly possibility that flutter will dominate
the Mobile App Development by 2023 -2024.
FUTURE SCOPE AS FLUTTER
DEVELOPER

• A f t er t he announcement of t he f irst t echnical preview
of H ummingbird, Flut t er has gained t he int erest of
w eb developers along w it h mobile developers.
• After the preview release of Flutter Web, the w ork is
in progress t o make Flut t er applicat ions compat ible
w ith deskt op t oo.
• This w ill allow t he developers t o build Flut t er
applications for Window s, Linux, and macOS.
• W hat more you need t o be excit ed about w hen an
advanced IoT t echnology can be embedded w ith t he
Flut t er plat f orm.
WHAT's NEXT IN FLUTTER?

• A s f lut t er is bet t er t han all ot her cross plat f orm
f ramew orks.
• So t he companies are t hinking t o build t here nat ive
apps in f lut t er.
• Since t he f lut t er communit y is increasing day by day,
t here w ill be demand of f lut t er developers in f ut ure.
• It 's predict ed t hat f lut t er may replace android
development .
• Thus w e conclud that flutter w ill be the future of
mobile app development .
