How to retrieve text value from RichText in flutter?

问题

以下是Flutter代码部分的翻译：

  1.    Column(
  2.               mainAxisAlignment: MainAxisAlignment.center,
  3.               crossAxisAlignment: CrossAxisAlignment.start,
  4.               children: <Widget>[
  5.                 Padding(
  6.                   padding:
  7.                       const EdgeInsets.only(bottom: LuminaSpacing.extraTiny),
  8.                   child: RichText(
  9.                     key: Key('last_updated'),
  10.                     textAlign: TextAlign.end,
  11.                     text: TextSpan(
  12.                       text: '${_localize.last_updated}: ',
  13.                       style: wldTheme.textTheme.display1,
  14.                       children: <TextSpan>[
  15.                         TextSpan(
  16.                             text: '${settingStore.lastCheckinTime}',
  17.                             style: wldTheme.textTheme.body1),
  18.                       ],
  19.                     ),
  20.                   ),
  21.                 ),

以下是Appium Java代码部分的翻译：

  1. FlutterFinder ele = new FlutterFinder(driver);
  3. System.out.println("Last update: "+ele.byValueKey("last_update"));
  4. // System.out.println("Last update: "+ele.byValueKey("last_update").getText());  // It waits for long duration

输出结果为：

  1. Last update: [pro.truongsinh.appium_flutter.finder.FlutterElement@870fb657 -> unknown locator]
英文:

Here's the Flutter code:

  1.    Column(
  2.               mainAxisAlignment: MainAxisAlignment.center,
  3.               crossAxisAlignment: CrossAxisAlignment.start,
  4.               children: &lt;Widget&gt;[
  5.                 Padding(
  6.                   padding:
  7.                       const EdgeInsets.only(bottom: LuminaSpacing.extraTiny),
  8.                   child: RichText(
  9.                     key: Key(&#39;last_updated&#39;),
  10.                     textAlign: TextAlign.end,
  11.                     text: TextSpan(
  12.                       text: &#39;${_localize.last_updated}: &#39;,
  13.                       style: wldTheme.textTheme.display1,
  14.                       children: &lt;TextSpan&gt;[
  15.                         TextSpan(
  16.                             text: &#39;${settingStore.lastCheckinTime}&#39;,
  17.                             style: wldTheme.textTheme.body1),
  18.                       ],
  19.                     ),
  20.                   ),
  21.                 ),

I'm using appium with java to automate my test cases

Here's my code:

  1. FlutterFinder ele = new FlutterFinder(driver);
  3. System.out.println(&quot;Last update: &quot;+ele.byValueKey(&quot;last_update&quot;));
  4. // System.out.println(&quot;Last update: &quot;+ele.byValueKey(&quot;last_update&quot;).getText());  // It waits for long duration

The output I get is

  1. Last update: [pro.truongsinh.appium_flutter.finder.FlutterElement@870fb657 -&gt; unknown locator]

得分: 1

你需要创建一个类似这样的控制器：var textController = TextEditingController();，并将控制器与你的RichText小部件关联起来，使用这个控制器你可以这样获取文本的值：textController.text。

英文:

you need to create a controller like this: var textController = TextEditingController(); and aggregate the controller to your RichText widget, with this controller you can get the value of the text like this: textController.text
