Summary

TLDR本视频教程讲解了如何在Flutter Flow中构建应用的两种方法:随意尝试和系统地设置设计系统。强调了设计系统的重要性,它涵盖了从颜色和排版到表单或标题等大型元素的所有设计方面。视频指出,通过事先设置设计系统,可以显著提高开发速度和应用的可扩展性。设计系统允许开发者一次设计,多处使用,从而简化了开发流程。Flutter Flow的设计系统中心方法支持高效工作,使得设计和开发团队能够轻松协作,共享和重用API和代码库,从而实现快速和灵活的应用开发。

Takeaways

  • 😊 设计系统可以提高应用程序的速度和可扩展性
  • 😎 通过设计系统,可以预先设计组件并在整个应用程序中重用
  • 📐 设置颜色、字体和组件可以创建一致的外观和感觉
  • 🔨 Flutter Flow内置了设计系统,可以在任何地方引用
  • ✏️ 设计系统不仅包括视觉元素,还包括整个API和代码库
  • 🎨 设计系统使新增页面变得很容易
  • 😀 Flutter Flow专为设计系统优先的方法而构建
  • 🤝 设计系统随着团队规模的增长而扩展
  • 🌈 可以为组织构建和引用多个设计系统
  • 🌟 设置设计系统是构建实际应用程序的第一步

Q & A

  • 设计系统的两个主要好处是什么?

    -速度和可扩展性。设计系统可以重用设计元素,从而加快开发速度,并且随着应用程序的增长更容易扩展。

  • 在 Flutter Flow 中,设计系统融入了哪些步骤?

    -设计系统集成到了使用 Flutter Flow 构建应用程序的每一步。无论在哪里看到集成变量符号,都可以引用或绑定设计系统中的值。

  • 设计系统不仅包括什么样的视觉元素?

    -不仅包括颜色、字体和组件等视觉元素,还包括整个 API 和代码库。

😄 设计系统的好处

设置设计系统可以提高开发速度,因为可以重复使用元素而不需要每次都重新设计。也可以让应用更容易扩展,因为新的页面可以通过组合已经预设好的元素来构建。设计系统包括定义颜色、字体、组件等视觉元素,以及代码库和 API。

Keywords

💡设计系统

设计系统指在应用程序中预先设置的可重复使用的元素,包括颜色、字体、组件等。它可以提高速度和可扩展性。SCRIPT中提到设计系统是使用Flutter Flow的核心方法,可以将其集成到构建应用的每个步骤。

💡组件

组件是可重复使用的用户界面元素,如表单、标题、按钮等。SCRIPT中提到设计系统包括从颜色到更大的组件。预先设计组件可以加快开发速度。

💡可扩展性

可扩展性是指应用程序能够随着需求的增长而扩展的能力。SCRIPT中提到设计系统为应用的可扩展性奠定基础。

💡代码库

代码库是可重用的代码集合。SCRIPT中提到设计系统不仅包括视觉元素,还包括整个API和代码库。

💡风格设置

风格设置允许自定义应用程序的视觉样式,如颜色、字体等。SCRIPT中提到这是开始建立设计系统的第一步。

💡绑定

绑定是将界面元素的值链接到代码变量的方法。SCRIPT中提到Flutter Flow允许在任何地方将值绑定到设计系统中。

💡文本操作

文本操作是对文本执行的操作,如添加前缀等。SCRIPT作为绑定设计系统自定义函数的例子提到了这一点。

💡后端调用

后端调用是向服务器发出请求以访问后端服务和数据的方法。SCRIPT中将其作为绑定设计系统自定义函数的另一个例子。

💡砖块

比喻应用程序开发需要从零开始逐步构建的过程。SCRIPT中使用房屋砖块的比喻,说明使用设计系统可以避免这种情况。

💡隔离

隔离是指设计系统独立于应用程序其他部分的状态。SCRIPT中提到Flutter Flow没有隔离或隐藏设计系统,它已经集成到每个构建步骤中。

there are two ways to build and flutter

play00:02

flow first is just jumping in and

play00:04

playing around and that's great I do it

play00:06

all the time but when you're ready to

play00:08

start building a real app you should

play00:11

start by setting up your design system

play00:13

and you do that by coming into your

play00:15

theme settings on the bottom left here

play00:17

now a design system is just setting up

play00:19

or pre-making everything that you're

play00:21

going to use in your app basically

play00:23

anything that you will repeatedly use

play00:25

you should set up in your design system

play00:27

first and this covers everything from

play00:30

the smallest things like color and

play00:31

typography to larger elements like

play00:34

components like a form or header

play00:37

sections and the reason you want to

play00:38

slide up your design system first is

play00:40

because this will give you two things

play00:43

speed and scalability it will give you

play00:46

speed because instead of having to

play00:48

redesign a button everywhere in your app

play00:50

where a button occurs you can design it

play00:52

once and then just drop it in in real

play00:55

practical terms this means that instead

play00:57

of having to click 20 times to set up a

play00:59

that button every time you can click

play01:02

once and second it gives you scalability

play01:05

that is when your app grows and you need

play01:07

another page you already have the colors

play01:10

the types the components designed and

play01:12

built so creating that new page is not

play01:14

like building a house Brick by Brick but

play01:17

simply putting together a few rooms that

play01:19

were already pre-made and flutter flow

play01:21

was built with a design system Centric

play01:24

approach and I mean two things by this

play01:26

first the design system is integrated

play01:29

into every step of building your app

play01:31

nothing is siled or hidden so you can

play01:34

work efficiently that's why you'll see

play01:36

this set from variable symbol everywhere

play01:39

because you can reference or bind values

play01:41

to your design system anywhere where you

play01:43

see it so for instance if you have a

play01:45

custom function in your design system

play01:47

that adds a prefix to a string you could

play01:49

use it here with a simple text in an

play01:51

action

play01:52

or a back-end call never having to

play01:55

rewrite it

play01:57

and second as your team scales with more

play01:59

designers and developers building on

play02:01

flutter flow our design system

play02:03

capabilities grow as well multiple

play02:05

Design Systems that can be built and

play02:07

live in your organization that you can

play02:10

pull into different projects and these

play02:12

Design Systems don't just include visual

play02:14

elements like colors type and components

play02:16

but whole API and code libraries alright

play02:19

so let's jump in and start setting up

play02:21

our design system
