drawing drawing

Features

  • Circle percent indicator
  • Linear percent indicator
  • Multi-segment linear indicator
  • Toggle animation
  • Custom duration of the animation
  • Progress based on a percentage value
  • Progress and background color
  • Custom size
  • Left , right or center child for Linear percent indicator
  • Top, bottom or center child for Circular percent indicator
  • Progress Color using gradients

Getting started

You should ensure that you add the router as a dependency in your flutter project.

dependencies:
  percent_indicator: ^4.2.5

You should then run flutter packages upgrade or update your packages in IntelliJ.

Example Project

There is a example project in the example folder. Check it out. Otherwise, keep reading to get up and running.

Usage

Need to include the import the package to the dart file where it will be used, use the below command,

import 'package:percent_indicator/percent_indicator.dart';

Circular percent indicator

Basic Widget

new CircularPercentIndicator(
                  radius: 60.0,
                  lineWidth: 5.0,
                  percent: 1.0,
                  center: new Text("100%"),
                  progressColor: Colors.green,
                )

Complete example

  @override
  Widget build(BuildContext context) {

此儲存庫發佈的套件

使用的依賴

依賴清單 2 項

  • flutter{"sdk":"flutter"}
  • flutter_test開發依賴{"sdk":"flutter"}

如何選擇適合專案的儲存庫?

先依使用情境篩選,再比較專案活躍情況,最後到原始儲存庫確認使用要求。

  1. 透過儲存庫名稱、作者或描述搜尋,再依技術分類縮小範圍。
  2. 綜合星標、分支與最近推送比較專案;星標反映社群關注,不保證品質。
  3. 使用前在 GitHub 確認 README、授權條款與 Issues。
