Text and RichText are the two widgets to display text. Flutter provides several classes related to text. This, of course, prompts the question as to what parameters are there on the Text widget and what do they mean. Almost all apps need to display some text to the end users.
This code snippet shows us a couple of things: firstly, that the first parameter of the Text constructor is the string to be displayed secondly, we can override, or set, the style of the text using the style parameter. All that is required for multi-line text, is that your Text () Widgets’ width is limited by a parent widget. The text is broken into two Text widgets to allow for the styling of the actual counter value to be different from the preceding text. Text( text, maxLines: 2, overflow: TextOverflow.ellipsis, ). To get into it, we’re going to start off with a new Flutter project, which already displays text to indicate how many times the button has been pressed. Q3: Limit the number of lines and add ellipsis. If you’re after a more detailed discussion of strings, characters and how they’re displayed, you should check out the post, Mastering Styled Text in Flutter. Source Code for Demo App: import 'package:flutter/material.In this post we’re going to look at the Text widget in Flutter and some of the options you can tweak when displaying text within your app. So if those aren't enough to suit your needs, you can always create more!Ī custom RowWithOverflow widget that takes in a fixed height, an overflow widget, and all the children. Basically, all these convenient widgets you use every day, like Row or Column, are all RenderBox under the hood (that someone working on Flutter already implemented for you). In your case, you should look into extending MultiChildRenderObjectWidget. I just chopped the string if character exceeds some length and add ellipsis to it. (Please CMIIW) Right now I just use a simple and ugly workaround by using character count. If setting fixed height with a SizedBox (say height: 120 or whatever) sounds reasonable, you should go with this approach. The ellipsis behavior is controlled by ParagraphBuilder class which is a wrapper around native ParagraphBuilder object.
In your case, this means you cannot dynamically decide the height of your widget. Specifically, the ellipsis is applied to the last line before the line truncated by maxLines, if maxLines is non-null. Setting this to a non-empty string will cause this string to be substituted for the remaining text if the text can not fit within the specified maximum width. The downside of this solution is, you cannot set the parent ( CustomMultiChildLayout) size based on its children's size. The string used to ellipsize overflowing text.
In this widget, you are given (almost) full control of the flutter layout pipeline, you can measure the total available size, and more importantly, you can measure the size of each of your children, and then determine what to render. If needed, I can provide some example code, but I will first describe the approaches here and see if you can do it yourself. There are 2 approaches, one is kinda hard, the other one is harder. This is one of the harder questions on flutter layout. Example 1: text overflow ellipsis flutter Text( 'Introduction to Very very very long text', maxLines: 1, overflow: TextOverflow. Flutter widget that automatically sets the number of lines to be shown on a text with the Ellipsis text overflow type.
