RAVLbIK · December 26, 2022, 9:06am

Product: PDFTron Reader for Flutter

Product Version: 1.0.1-4

Please give a brief summary of your issue: Hello, i have problem when opening files on android emulator or real android device.
(Think of this as an email subject)

Please describe your issue and provide steps to reproduce it: Files aren`t opening from the first attemp sometimes. I can open to read the file only from the second or the third attemp. App was created on flutter. I havent any logs of this issue. How can i fix it? Also i have two questions, how can i handle errors when using DocumentView Widget and manual set colors palette of appBar in DocumentView?
(The more descriptive your answer, the faster we are able to help you)

Please provide a link to a minimal sample where the issue is reproducible: GitHub - RAVLbIK/reader.dart

Hi there,

Thank you for contacting Android Support forum,

For the document loading issue, could you please provide a minimal runnable sample to reproduce the issue from our end?

For the error handling, you can use this API for document opening errors:

For the app theming, you will need to override the PDFTronAppTheme style in the styles.xml file.
We don’t have a Flutter example, but it should be similar to our native Android sample here:

PDFTron/pdftron-android-samples/blob/master/CustomUI/app/src/main/res/values/styles.xml

<resources xmlns:tools="http://schemas.android.com/tools">

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.MaterialComponents.NoActionBar.Bridge">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/background_color</item>
        <item name="colorPrimaryDark">@color/utility_variant_color</item>
        <item name="colorAccent">@color/accent_color</item>
    </style>

    <style name="MyCustomAppTheme" parent="PDFTronAppTheme">
        <item name="colorPrimary">@color/background_color</item>
        <item name="colorPrimaryDark">@color/utility_variant_color</item>
        <item name="colorAccent">@color/accent_color</item>

        <!-- Style of status bar color -->
        <item name="android:statusBarColor" tools:targetApi="lollipop">@android:color/holo_blue_dark</item>

        <!-- Style of popup menu background color -->
        <item name="colorBackgroundFloating">@color/background_color</item>
