Learning a new UI engine is always tricky. Thankfully, the Flutter team has highlighted the basic widgets. For this code tutorial, we will focus on Row and Column, which lay out a list of child widgets in the horizontal and vertical direction respectively.
Move Row Content Automatically to Next Line in Flutter using Wrap Widget
To figure out how Row and Column work, we will start from 3 different mock-ups and lay them out using them. We will do this as part of an app with 3 screens one screen per example. For each example, we will have a rough sketch of what we want, with notes to describe how each part of the layout behaves. Why rough hand drawn sketches and not fancy mock ups done in Photoshop? Because I want to show you a simple process that you can apply to your own mock ups. Oh, and also because pen and paper is a very useful tool see Tip 3 of 4 tips to boost your software development career.
For this example, we will create a screen with a subtitle below the toolbar which is always shown, a call to action button at the bottom, which is also always shown, and some other content in between the two. Then, we convert the descriptions into Flutter widgets. For this example, we will create a widget that would most likely be used in a list. It has an icon on the left and one on the right, a title which itself is made up of an image, and 2 separate pieces of text one of those to be truncated as requiredand a description to be restricted to 2 lines.
From one of your favourite apps, or an app you are working on now, choose a screen, and work out how you would lay it out in Flutter. Mobile native app developer. Past apps range from start ups to large tech Google and non tech British Airways companies. Great post.
There is not much documentation on how to use the layout widgets together so this is very helpful. One anomaly in your first design. If there is an entry form in the middle, the bottom footer slides up with the keyboard. Do you know a way to get the keyboard to cover the bottom footer instead?

Or will require more lines than 2, but' ' we only show 2 lines maximum f f f f f f f f f f f f f f f. It may fit on 2 lines, '.But using the Wrap widget of Flutter we can solve this problem within a few minutes.
Wrap widgets automatically align the Widgets items one by one and if the Row is filled then it will move row content automatically to next line in flutter. Wrap widgets can support both Horizontal alignment and Vertical Alignment like Row and Column widgets in flutter.
Using the Wrap widget we can adjust multiple widgets at once without disturbing each other. Import material. Now we would call our void main runApp method and call the MyApp main root class. Now we would create a function named as sampleFunction and inside the function simply print a Console message using Print method.
Creating Wrap widget in Center widget and then we would put multiple Raised Button widgets inside it, which would align automatically. Every Raised Button widget is Wrap in Container widget to specify margin values.

AutoSizeText behaves exactly like a Text. The only difference is that it resizes text to fit within its bounds. Note: AutoSizeText needs bounded constraints to resize the text. More info here. The maxLines parameter works like you are used to with the Text widget. If there is no maxLines parameter specified, the AutoSizeText only fits the text according to the available width and height.
It measures the resulting text and rescales it to fit within its bonds. You can however set the allowed range of the resulting font size. With minFontSize you can specify the smallest possible font size. If the text still doesn't fit, it will be handled according to overflow. The default minFontSize is This is useful if the TextStyle inherits the font size and you want to constrain it.
You can synchronize the font size of multiple AutoSizeText. They will fit their boundaries and all AutoSizeText in the same group have the same size. That means they adjust their font size to the group member with the smallest effective font size.
How to use Row and Column in Flutter with examples
Note: If a AutoSizeText cannot adjust because of constraints like minFontSizeit won't have the same size as the other group members. An instance of AutoSizeGroup represents one group. Pass this instance to all AutoSizeText you want to add to that group.
You don't have to care about disposing the group if it is no longer needed. Important: Please don't pass a new instance of AutoSizeGroup every build.Keep in touch and stay productive with Teams and Officeeven when you're working remotely. Microsoft Excel can wrap text so it appears on multiple lines in a cell. You can format the cell so the text wraps automatically, or enter a manual line break.
On the Home tab, in the Alignment group, click Wrap Text. Data in the cell wraps to fit the column width, so if you change the column width, data wrapping adjusts automatically. If all wrapped text is not visible, it may be because the row is set to a specific height or that the text is in a range of cells that has been merged.
On the Home tab, in the Cells group, click Format. To specify a row height, click Row Heightand then type the row height that you want in the Row height box. To start a new line of text at any specific point in a cell:.

Row and Column let you align child widgets horizontally and vertically. If you are a web developer, you can compare them with a div with the following properties in CSS:. This is a good example because in a list item the information is aligned horizontally.
First, we need an avatar for our contact. Flutter provides us with a very nice widget called CircleAvatar that gives you a ready-to-use circular widget specially made for this purpose. So we will use that one. We define a background color for our avatar and take the first letter of our contact instead of an image.
For the name of our contact, we will be using the Text widget obviously. First of all, our Row is too close to the left and the top. Somehow we need to add distance between the Row and the parent widget.
We will use a Container for that with small padding. The next thing we probably want to fix is the fact that the text and the avatar are too close to each other. We will put a SizedBox between them with the desired width. Lastly, we wrap our Row inside an InkWell. InkWell provides us with GestureDetector which gives us an onTap callback plus visual feedback.
Of course, there are many more use cases where you would be using the Row widget, but the principle stays the same. Row and Column have the same alignment properties, they work for the mainAxisAlignment horizontal in Row and vertical in Column and crossAxisAlignment the opposite of mainAxis. These 2 alignment categories can be set to one of the following values:. It will then look like this:. You can try the other properties yourself to see what happens if you are a web developer, it works the same as flex properties.
A very good example of when Column comes in handy is probably alignment of form widgets in a page. I will write a separate post about how to properly use a form in Flutter. This post explains the basic working of Row and Column which align their children in a horizontal and vertical way. There are more advanced alignments within Row and Columnlike how much each child should occupy, which I will explain in a separate post.
Change your preferences any time. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I want wrap text as text grows. I searched through and tried wrap with almost everything but still text stays one line and overflows from the screen. Does anyone know how to achieve this? Any help is highly appreciated! In a project of mine I wrap Text instances around Container s. This particular code sample features two stacked Text objects.
If it's a single text widget that you want to wrap, you can either use Flexible or Expanded widgets. For multiple widgets, you may choose Wrap widget. For further details checkout this. If you are using Text inside a Rowyou can put above Text inside Expanded like:. You can use Flexible, in this case the person. Learn more. Flutter- wrapping text [duplicate] Ask Question.

I think it's something to do with stack or positioned or draggable. Am I right? You might try to force a fixed width to a container: I edited my answer. Thank you so much it worked perfectly. You just made my day! Try the Flexible widget instead. Hardcoding containers width should not be necessary. Do you have any idea?

Wrap text in a cell

From the email thread, he's looking to create a horizontal layout with an icon on the left and a text on the right where the size of the widget expands as the amount of text increases until it hits its width constraints and at that point the text starts wrapping. Current proposal is to add an enum to Flexible about whether the child should be given tight or loose constraints.
Current behavior today is tight constraints, but loose constraints would satisfy cooler-king 's use case. I was playing around with nested Flex widgets and hit this situation, which I think is probably the same as what cooler-king described. In the following example code, the description text overflows off the right side of the screen instead of wrapping. Interestingly if I take the Row out leaving just the Column the text wraps properly. I was able to solve my problem by wrapping the Column here in a Flexible.
I don't recall from the mailing list whether you eventually found a solution that worked for you. This still happens in the latest master Channel master, v0.
The Row is giving its children unlimited horizontal space to work with. Try wrapping the Row 's second child in an Expanded widget. That will cause that child to fill the remaining space instead of being given unlimited space to work with.
